Are you trying to build a transactional memory system for the JVM or your own Java code?

Hi Jon,

I need this for an undo log of a transactional memory system with pessimistic locking/eager version management. Am 9.

If you don't want something to be garbage collected then simply don't dereference it. On Thu, Mar 9, 2017 at 12:38 PM Christian Hagedorn <ch-hagedorn at hispeed.ch> wrote: Hi,

I want to implement an undo functionality and thus need to access an oop even when it is out of scope in the Java code. How can I pin such an oop to avoid garbage collection of its used memory? Best regards, Christian
