Describe the bug
When using Java 11 and maven and lombok and when you have a package-info.java somewhere that does not have a package statement, the compiler generates an NPE.

To Reproduce
Clone and follow the instructions:

https://github.com/Masterxilo/javac-11-mvn-bug-lombok-packageinfo-bug

mvn clean compile

Just to be certain, the problem does not occur if you remove your lombok dependency?

thanks for the fast response! I will check it out. Just so you know, we have many reports and only limited time, so before we pull and compile, we want to make sure there is a real problem.

I could also reproduce this problem without using mvn:

javac -source 11 -target 11 -cp lombok-1.18.9.jar src/main/java/mypackage/package-info.java
