Required class information missing after upgrade to version higher than 42.2.14 #2008

okarmusk · 2021-01-02T11:10:11Z

I've upgraded driver to version 42.2.18, then Required class information missing error appeared. Source code with traces bellow. To omit error i had to back to version 42.2.14.

So do we know what is causing this error ? What information is required ?

okarmusk · 2021-01-02T12:59:57Z

This stack trace is only one information what i received. People on stackoverflow already know issue, here is the link: stackoverflow issue

Issue is at least strength cause configuration lunched on newest Hibernate versions with pgjdbc version lower or equal to 42.2.14 works. Only if i changed pgjdbc driver version it failed, no metter of Hibernate version.

davecramer · 2021-01-02T13:44:02Z

I created https://github.com/davecramer/hibernate_test and this works fine. If you can provide me with a small test code that fails that will help

okarmusk · 2021-01-02T14:08:03Z

First difference what i noticed is that i'm using import javax.persistence.* for JPA annotations, in your code there are:

import org.hibernate.annotations.Table;
import org.hibernate.annotations.Entity;
import org.hibernate.annotations.GenericGenerator;

Maybe if i use hibernate as a JPA provider i need to define something additional in persistence.xml what hibernate annotation contains by default...

davecramer · 2021-01-02T14:11:17Z

Please provide me with code that breaks.

Previous persistence.xml contains mock Data class. Right class tag in persistence.xml looks like:

Services CurrencyQuotationService and ForexNotificationService are only middle ware services.

EntityManagerProvider contains nothing special, but in case of need:

            synchronized (EntityManagerProvider.class) {
                entityManager = emf.createEntityManager();
                logger.info("EntityManager created");

                return entityManager;

What version of hibernate are you using ?

okarmusk · 2021-01-02T14:56:17Z

5.4.27.Final for core and entitymanager. i tried different hibernate versions, basically i've checked it since 5.4.23.Final.

davecramer · 2021-01-02T14:58:47Z

Can you take my code and make it fail by changing the annotations ?

vlsi · 2021-01-02T15:37:16Z

Here's a relevant jandex issue: smallrye/jandex#92

okarmusk · 2021-01-02T15:37:33Z

I have no access to write to repository. Can you add me?

Btw, when i ran your code from master in intellij it works. Problems started for compiling stuff manually and run it by command.
What i changed to reproduce issue:
First i changed Data.java to:

package org.postgresql.model;

import javax.persistence.*;

@Entity
@Table(name = "data")
public class Data {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "id")
    private Long id;

    public Long getId() {
        return id;
    }
    public void setId(Long id) {
        this.id=id;
    }
}

Next i change build.gradle to:

plugins {
    id 'java'
}

group 'org.postgresql'
version '1.0-SNAPSHOT'

repositories {
    mavenCentral()
}

dependencies {
    compile group: 'org.hibernate', name:'hibernate-core', version: '5.4.25.Final'
    compile group: 'org.postgresql', name: 'postgresql', version: '42.2.18'
    testCompile group: 'junit', name: 'junit', version: '4.12'
}

jar {
    manifest {
        attributes(
                'Class-Path': configurations.compile.collect { it.getName() }.join(' '),
                'Main-Class': 'org.postgresql.Test'
        )
    }
    from { configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } }
}

Other lines without change. i run code by java -jar build/libs/hibernate_test-1.0-SNAPSHOT.jar.

I presume you have a classpath setup.

When I run this from inside intellij it runs fine.

okarmusk · 2021-01-02T17:02:47Z

I get the same error if i used implementation instead of compile in build.gradle. Did you changed it?
Class-Path was also defined in jar {...} section in build.gradle.

davecramer · 2021-01-02T18:02:40Z

I did and can replicate the error now. Interestingly if I run it inside intellij it works fine. If I run it outside it does not.

The type it is trying to find the path to is

private final Provider timeZoneProvider;

Strangely it is looking it up as a NESTED instead of PARAMATERIZED

The annotation it is looking for is @nullable which I can't find anywhere.

Looks like Provider was added in 1e1f3c4 which is likely the reason.

vlsi · 2021-01-02T19:03:46Z

There are two types of possibilities of the bugs:

a) javac bugs. Old (e.g. pre 1.8u202) had several known bugs that caused javac to produce invalid bytecode
b) org.jboss:jandex bugs when parsing class files with type annotations

If I rebuild pgjdbc with Java 11 (just in case), and add compile 'org.jboss:jandex:2.2.2.Final', the error becomes

public class LruCache<Key extends @NonNull Object, Value extends @NonNull CanEstimateSize>
    implements Gettable<Key, Value> {

javap -verbose -p LruCache.class

Signature: #116                         // <Key:Ljava/lang/Object;Value::Lorg/postgresql/util/CanEstimateSize;>Ljava/lang/Object;Lorg/postgresql/util/Gettable<TKey;TValue;>;
SourceFile: "LruCache.java"
RuntimeVisibleTypeAnnotations:
  0: #119(): CLASS_TYPE_PARAMETER_BOUND, param_index=0, bound_index=0
    org.checkerframework.checker.nullness.qual.NonNull
  1: #119(): CLASS_TYPE_PARAMETER_BOUND, param_index=1, bound_index=1
    org.checkerframework.checker.nullness.qual.NonNull

This represents the two @NonNull annotations.

Unfortunately, it is not clear which specification declares that optional class bound should reserve "bound_index=0", however, OpenJDK implementation does adjust the index.
Interestingly enough, there was a recent fix in the area of reflection vs type annotations: openjdk/jdk@9d7f8bc

vlsi · 2021-01-03T13:19:48Z

Just in case, Value::Lorg/postgresql/util/CanEstimateSize; in the signature attribute means something like Value extends Object & CanEstimateSize, so bound_index=1 means that the annotation is placed at CanEstimateSize rather than at Object.

It looks like jandex does not handle that :-(

davecramer · 2021-01-03T13:21:35Z

So at this point my recommendation would be not to use the JPA annotations.

vlsi · 2021-01-03T13:49:39Z

I've created jandex issue: smallrye/jandex#99

The takeaway for pgjdbc is we might want to verify that the produced bytecode is parseable with jandex, asm, and probably other bytecode analysis frameworks.

bokken · 2021-01-03T14:08:40Z

Would incorporating spotbugs be sufficient to test asm? I am not certain how it generally handles case of bytecode it does not understand. I do know that many of the jdk 8 changes caused spotbugs (findbugs) to fail until asm was updated.

@vlsi i guess fix has been merged, when next release is planned? If code is merged should i close the issue, or should i wait till next release and verify if it works?

vlsi · 2021-01-10T10:35:08Z

@okarmusk , do you think you could verify if #2010 solves the issue for you?

I wanted to add Java 11 test with Jandex (as javac 11 produces slightly different java8 bytecode), however, it turned out Java11+ and PostgreSQL12+ have issues with SSL client certificates which I am analyzing at the moment.

I got a similar error (java.lang.ClassNotFoundException: org.postgresql.Driver) after upgrading postgresql driver from 42.2.2 to 42.3.4. After a lot of trial and error, I found out that postgresql in versions starting from 42.2.13 fails to be properly recognized by the classloader if there is a INDEX.LIST file in the JAR archive. Project in which the issue can be reproduced is in my github repo "DBTest".

    }
}

executes fine both inside intellij and manually using 42.3.6 and jdk 1.8

Have you tried launching it after building a JAR archive? I've added simple ones to my repo https://github.com/hiroSzymon/DBTest to make testing and verification easier. The only difference between the JARs is the mentioned INDEX.LIST file.

I ran java -cp ./lib/postgresql-42.3.6.jar:target/classes LoadDriver locally

I ran java -cp ./lib/postgresql-42.3.6.jar:target/classes LoadDriver locally

This way it works. The issue happens only when running it with the JAR.

davecramer · 2022-06-02T15:43:55Z

Did you add the services file to the jar ? https://github.com/pgjdbc/pgjdbc/tree/master/pgjdbc/src/main/resources/META-INF/services

hiroSzymon · 2022-06-02T15:51:00Z

No. The only services file is in the postgresql-42.3.4.jar downloaded from maven repository (to be sure, I've compared SHA-256 between the maven one and downloaded directly from https://jdbc.postgresql.org/download/postgresql-42.3.4.jar and they are equal).

so I cloned your repo and built it using mvn package
now what ?

vlsi · 2022-06-02T16:09:06Z

I believe the issue has been fixed in 42.2.19 2df6c97, and 42.3.0 f3301c1

@hiroSzymon , please file a new issue with the test case

As vlsi suggested, I've created new issue #2527.
To reproduce, you have to uncomment or add <index>true</index> in pom.xml before building.
