When returning from the last Java frame back to vm and hitting a safepoint poll on that last return we sometimes have a last java frame but no vframe. This seem to be a bug in itself, handled in: 8263576
Other places which uses vframe NULL checks it before, so let's do that in GetCurrentLocationClosure also. Testing: nsk jdi/jvmti, jdk jdi, jck vm and t1-3. ------------- Commit messages: - Check vframe non-null Changes: https://git.openjdk.java.net/jdk/pull/3010/files Webrev: https://webrevs.openjdk.java.net/?repo=jdk&pr=3010&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8261262 Stats: 9 lines in 1 file changed: 0 ins; 3 del; 6 mod Patch: https://git.openjdk.java.net/jdk/pull/3010.diff Fetch: git fetch https://git.openjdk.java.net/jdk pull/3010/head:pull/3010 PR: https://git.openjdk.java.net/jdk/pull/3010
