A previous cleanup #14642 accidentally omitted the fact that an `Array.newInstance` call in `BytecodeDescriptor::parseSig` is intended to propagate `IllegalArgumentException` to `MethodType::fromMethodDescriptorString`. This bug is discovered in a recent cleanup for `BytecodeDescriptor` in #24978.
Instead of restoring the original `newInstance` call, this patch catches the `UnsupportedOperationException` thrown by `Class::arrayType` to because the cause IAE thrown by `newInstance` has no message at all. The existing reporting system in `BytecodeDescriptor::parseMethod` includes the whole malformed descriptor string in the error message, which can be triggered by returning `null` in `parseSig`. ------------- Commit messages: - Add bug number - 8366028: MethodType::fromMethodDescriptorString should not throw UnsupportedOperationException for invalid descriptors Changes: https://git.openjdk.org/jdk/pull/26909/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=26909&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8366028 Stats: 31 lines in 2 files changed: 27 ins; 0 del; 4 mod Patch: https://git.openjdk.org/jdk/pull/26909.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/26909/head:pull/26909 PR: https://git.openjdk.org/jdk/pull/26909
