The patch looks similar to the original. As a quick test, I changed the threshold to 10 (from 90) to force the creation of helper methods and it fails as expected with:


$ java -Xlog:init=debug -XX:+UnlockDiagnosticVMOptions -XX:+BytecodeVerificationLocal -version
Error occurred during initialization of boot layer

Do you want to continue with this issue?
