JDK-8281450: Remove unnecessary operator new and delete from ObjectMonitor #7377

@tstuefe tstuefe commented Feb 8, 2022

Trivial (?) patch to remove ObjectMonitor operator new and delete. Since ObjectMonitor derives from CHeapObj, we don't need those.

This also solves the problem that the local new overrules the NMT category flag set in CHeapObj (both currently are mtInternal, so the problem is theoretical).

Hi Thomas,

Initially I was a bit confused as I found the ADLC definition of CHeapObj :) But now I see this is a trivial cleanup.

Thanks,
David

Thanks, David

:-) I keep having this problem with our Arena code. Reminds me that I wanted to ask Vladimir K whether it's ok to rename the ADLC versions...

Thanks for the thumbs up!
