Hi Here is summary of such "non test-specific" bugs:
Following bugs affect all (or mostly all) tests: JDK-8202884 <https://bugs.openjdk.java.net/browse/JDK-8202884>SA: Attach/detach might fail on Linux if debugee application create/destroy threads during attaching JDK-8204994 <https://bugs.openjdk.java.net/browse/JDK-8204994>SA might fail to attach to process with "Windbg Error: WaitForEvent failed" JDK-8197591 <https://bugs.openjdk.java.net/browse/JDK-8197591>Tests failing with App waiting timeout JDK-8203364 <https://bugs.openjdk.java.net/browse/JDK-8203364>Some serviceability/sa/ tests intermittently fail with java.io.IOException: LingeredApp terminated with non-zero exit code 3 and the similar bug for Solaris-SPARC JDK-8193639 <https://bugs.openjdk.java.net/browse/JDK-8193639> tests failing intermittently with Error attaching to process: Can't create thread_db agent! SA might fail connecting to any process because of JDK-8202884 <https://bugs.openjdk.java.net/browse/JDK-8202884>, JDK-8204994 <https://bugs.openjdk.java.net/browse/JDK-8204994>. Also all tests relying on LingeredApp might affected by JDK-8197591 <https://bugs.openjdk.java.net/browse/JDK-8197591>, JDK-8203364 <https://bugs.openjdk.java.net/browse/JDK-8203364>. You have seen a lot of failures caused by https://bugs.openjdk.java.net/browse/JDK-8202884 <https://bugs.openjdk.java.net/browse/JDK-8202884> because it is a Linux-specific bug which is often reproduced on multi-core host.
