--- Comment #12 from Jaikiran Pai <jaiki...@apache.org> --- Thank you for testing this and posting the results. It's good to know that the deadlock no longer exists. So this bug is actually fixed. As for the underlying IOException which was triggering this deadlock, which is now reported back to the System.err: [junitlauncher] Caused by: java.io.IOException: Pipe broken [junitlauncher] at java.base/java.io.PipedInputStream.read(PipedInputStream.java:321) [junitlauncher] at java.base/java.io.PipedInputStream.read(PipedInputStream.java:377) [junitlauncher] at java.base/java.io.InputStream.read(InputStream.java:205) [junitlauncher] at org.apache.tools.ant.taskdefs.optional.junitlauncher.LauncherSupport$SysOutErrStreamReader.run(LauncherSupport.java:525) [junitlauncher] ... 1 more I am not sure why that would be the case. Is that impacting any of the test runs? I will pay a closer attention to the code in this task to see if there's a possibility which could trigger this error and if so whether it's harmless enough to be ignored. -- You are receiving this mail because: You are the assignee for the bug.
