This fixes a bug in the test test/jdk/com/sun/jdi/EATests.java that caused timeout failures when graal is enabled.
The fix is to avoid suspending all threads when a breakpoint is reached and then resume just the main thread again. This pattern was used in the test case EAMaterializeLocalAtObjectPollReturnReturn. It caused timeouts because graal threads remained suspended and, running with -Xbatch, the main thread waited (with timeout) for completion of compile tasks. The fix was applied to all breakpoints in the test. All explicit suspend calls now apply only to the main test thread and all explicit resume calls apply to all java threads. Testing: duration of the test case EAMaterializeLocalAtObjectPollReturnReturn is reduced from 30s to 10s. ------------- Commit messages: - 8255381: com/sun/jdi/EATests.java should not suspend graal threads Changes: https://git.openjdk.java.net/jdk/pull/1625/files Webrev: https://webrevs.openjdk.java.net/?repo=jdk&pr=1625&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8255381 Stats: 91 lines in 2 files changed: 33 ins; 10 del; 48 mod Patch: https://git.openjdk.java.net/jdk/pull/1625.diff Fetch: git fetch https://git.openjdk.java.net/jdk pull/1625/head:pull/1625 PR: https://git.openjdk.java.net/jdk/pull/1625
