In a test that stresses metaspace (such as `vmTestbase/vm/mlvm/hiddenloader/stress/oome/metaspace/Test.java`) that also uses `-Xcomp -XX:-TieredCompilation`, we've seen a failure in `TranslatedException.<clinit>` due to exhausted metaspace:
java.lang.OutOfMemoryError: Metaspace at jdk.internal.vm.TranslatedException.encodeThrowable([java.base@21-galahadeestaging](mailto:java.base@21-galahadeestaging)/TranslatedException.java:176) at jdk.internal.vm.TranslatedException.<clinit>([java.base@21-galahadeestaging](mailto:java.base@21-galahadeestaging)/TranslatedException.java:61) at jdk.internal.vm.VMSupport.encodeThrowable([java.base@21-galahadeestaging](mailto:java.base@21-galahadeestaging)/VMSupport.java:171) This PR pushes a fix such that this exception is properly handled in the VM (i.e. causing a compilation bailout) instead of leading to a VM crash. The PR includes 2 bits of debug code guarded by system properties that enable the handling to be tested in libgraal. The test itself is not included as libgraal is not part of OpenJDK. ------------- Commit messages: - handle exception in TranslatedException.<clinit> (JDK-8313899) Changes: https://git.openjdk.org/jdk/pull/15198/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=15198&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8313899 Stats: 43 lines in 3 files changed: 41 ins; 1 del; 1 mod Patch: https://git.openjdk.org/jdk/pull/15198.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/15198/head:pull/15198 PR: https://git.openjdk.org/jdk/pull/15198
