[hibernate-dev] Byte-buddy: default enhancer in 5.3 ? [HHH-11253]

[Sanne Grinovero]

I found a couple more issues related to Byte Buddy which probably
should be fixed before we can make it the default.

I've solved the trivial ones, but there's one more problem which I
couldn't nail down yet: the testsuite is using a significant amount of
additional memory when all tests default to the Byte Buddy based
enhancer: the requirements are rocketing from about 150MB to 4GB.

A further complication is that for some reason Flight Recorder crashes
when connecting to the ORM testsuite; I've tried both versions coming
with JDK8 and JDK9 they both fail. I finally manged to get some
recordings from CLI tools so I hope to know more soon.

I also noticed that the support for
hibernate.bytecode.provider=bytebuddy was not documented; that might
explain some lack of feedback on such issues. Makes me think that
maybe this wasn't tested much yet?

Thanks,
Sanne
