Hi Florian, Thanks for doing this.
Do you have any more context on what RPMs/jars are using what methods of Unsafe? such information would be useful to correlated with that on maven central. I think i can guess some aspects e.g.: monitorEnter | (Ljava/lang/Object;)V | 1 monitorExit | (Ljava/lang/Object;)V | 1 On Mar 4, 2014, at 9:22 PM, Florian Weimer <fwei...@redhat.com> wrote: > Out of curiosity, I looked at JAR files in all RPMs in Fedora rawhide (the > development version of Fedora that will turn into Fedora 21) and counted the > number of RPM packages which had Java classes referencing individual methods > in sun.misc.Unsafe.

I don't have data yet from maven central but i know some jars that use Unsafe are quite popular. Paul.
