Intermittent failure in ConcurrentTransactionTests on windows

[fmbenhassine]

org.springframework.batch.core.test.concurrent.ConcurrentTransactionTests.testConcurrentLongRunningJobExecutions fails intermittently on windows from the command line with the following error:

This test also fails for me when running all tests in spring-batch-core. The test passes in isolation. I'm on MacOS. Let me know if I can provide additional information.

@nfjcore I'm also on MacOS (Catalina v10.15.7) and this test didn't fail up until now when I build locally with Java 8:

$ java -version
java version "1.8.0_181"
Java(TM) SE Runtime Environment (build 1.8.0_181-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode)

It did not fail neither on our CI server. But if you say it fails on your machine, I trust you.

Let me know if I can provide additional information.

Yes, please. Which java version do you use? Do you use the maven wrapper or your local maven installation?

[nfjcore]

I am using the following java version:

java -version
openjdk version "1.8.0_282"
OpenJDK Runtime Environment (AdoptOpenJDK)(build 1.8.0_282-b08)
OpenJDK 64-Bit Server VM (AdoptOpenJDK)(build 25.282-b08, mixed mode)

I should have specified it before, but org.springframework.batch.core.test.concurrent.ConcurrentTransactionTests fails only when I right click spring-batch-core/src/test/java and select Run 'All Tests' in Intellij.

If I'm using the Maven wrapper LdifReaderTests.testValidRun is failing. But I guess this is beyond the scope of this issue.

Seems to be resolved with #3856 (5 consecutive builds without failure).
