On AIX the test test/hotspot/jtreg/serviceability/jvmti/RedefineClasses/RedefineLeakThrowable.java runs into this error:

I tested with higher iteration value in main of RedefineLeakThrowable so see if it is not a leak and with 23m it passes too on AIX with higher iteration value. For some reason, with product binaries 21m was sufficient too (but fastdebug needed a bit more). Should we keep the old MetaSpace value 17m for non - AIX ? ------------- Commit messages: - Adjust start section of the test - JDK-8319375 Changes: https://git.openjdk.org/jdk/pull/16553/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=16553&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8319375 Stats: 2 lines in 1 file changed: 0 ins; 0 del; 2 mod Patch: https://git.openjdk.org/jdk/pull/16553.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/16553/head:pull/16553 PR: https://git.openjdk.org/jdk/pull/16553
