Comments
EVALUATION This issue is seen with hs20 b02. This was before the fix for 6983204 (which exposes the issue in 7009266) was integrated so the crash and verification errors are not related to 7009266. Suspicion is the initialization with the concurrent zero filling thread. Trying with latest JVM with the fix for 6983204 removed.
