IllegalArgumentException can be thrown when running an uber jar on a shared drive

[madalinaandreeab]

Hi,

I recently upgraded from spring boot 3.1.7 to 3.2.5 and I am getting an IllegalArgumentException when I am using my service, which is stored as a jar on a shared drive.

I created a simple Eureka server app to demonstrate the issue: https://github.com/madalinaandreeab/eureka-server-demo

I placed the eureka-server-demo-0.0.1-SNAPSHOT.jar file in the \myshare\drive\users\mab\ shared drive and I started the service using the following command:
java -jar \\myshare\drive\users\mab\eureka-server-demo-0.0.1-SNAPSHOT.jar

The service starts successfully, but when I access the Eureka UI at http://localhost:8761/, I am getting the error below.

Please notice that the error refers to the C:\drive\users\mab\eureka-server-demo-0.0.1-SNAPSHOT.jar path which doesn't exist; The right path would be \\myshare\drive\users\mab\eureka-server-demo-0.0.1-SNAPSHOT.jar.

Thank you!

Thanks for the report. Can you confirm that your app works with Spring Boot 3.2.5 with the "classic" loader fallback implementation as described in the release notes?

[madalinaandreeab]

Hi @scottfrederick ,

Yes, it does. I have the following plugin in the pom file of the original service where I discovered the issue:

<plugin>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-maven-plugin</artifactId>
	<configuration>
		<mainClass>${mainClass}</mainClass>
	</configuration>
	<executions>
		<execution>
			<goals>
				<goal>repackage</goal>
			</goals>
			<configuration>
				<loaderImplementation>CLASSIC</loaderImplementation>
			</configuration>
		</execution>
	</executions>
</plugin>

Thanks!

Hello please note that windows share drive can be as follow
"\server\Share$"
Or
"\server\Share\dir1\DIR2"
Or
"\server\Share\my path with spaces"
Or
"\server\Share\because\IamFrench\Iuse èéà"

I mean we can have specific accent characters with or without spaces even if those are not good practises sometimes we do not choose where the users want to store the jar

Thank you

Hi,

Upon further investigation, I believe this issue may be connected to #39675.

Thanks!
