FYI I'll be on vacation for 3 weeks from May 1. An array does not have an internal name. Changing `ofInternalName` to accept arrays seems not right. What is the issue of calling `ClassDesc.ofDescriptor` for arrays? Have you considered `internalName` to return an `Optional`? ------------- PR Comment: https://git.openjdk.org/jdk/pull/13598#issuecomment-1524102955 PR Comment: https://git.openjdk.org/jdk/pull/13598#issuecomment-1524105274
