Tested on Linux x86_64 (fastdebug) Test: `vmTestbase_nsk_jdi`, `vmTestbase_nsk_jdwp`, `vmTestbase_nsk_jvmti` `vmTestbase_nsk_jdb' and `jdk_jdi` - [x] default, no failure - [x] ShenandoahGC + aggressive, one timeout [1] - [x] ZGC with -Xmx2g -XX:ZCollectionInterval=0.01, one timeout - [x] ZGC with -XX:ZFragmentationLimit=0.1, no failure [1] `vmTestbase/nsk/jvmti/scenarios/allocation/AP04/ap04t001/TestDescription.java` I pushed update that removed the block, could you please run it through Oracle's internal tests? Thanks! ------------- PR: https://git.openjdk.org/jdk/pull/9168
