We're seeing the mentioned test issue intermittently in our nightlies. Bug: https://bugs.openjdk.java.net/browse/JDK-8205654 Webrev: http://cr.openjdk.java.net/~clanger/webrevs/8205654.11u-dev.0/ Original Change: http://hg.openjdk.java.net/jdk/jdk/rev/67537bbafd7f Original review discussion: https://mail.openjdk.java.net/pipermail/serviceability-dev/2019-February/026883.html The change improves the way how jcmd explores running Java processes on Linux. It'll then try to use the proc file system first to get the necessary information before trying to attach via the attach framework. The original patch needs 2 modifications: 1. In src/jdk.jcmd/share/classes/sun/tools/common/ProcessArgumentMatcher.java I had to add the fix of JDK-8218705. The bug is not visible unfortunately but it seems something was forgot in the original commit. The change for JDK-8218705 is: http://hg.openjdk.java.net/jdk/jdk/rev/50c1b0a0f1e8 2. In test/lib/jdk/test/lib/util/JarUtils.java I had to take over some upstream coding from jdk/jdk to provide the JarUtils support that is needed by the new testcase "TestProcessHelper". Thanks Christoph
