Is the memory leak bug still present for java agents using imported .jars in Domino 12?

Question

I've read here that attaching .jar files to domino agents causes a memory leak and the solution is to add them to jvm/lib/ext and restart the jvm. However I understand that putting them in the /ext folder can cause some security issues (see comments).

Is the memory leak problem still the case in Domino 12.0?

Would using the OpenNTF Domino API solve this issue?

Are there any long-term memory leak issues in just using .jars in the /ext folder?

Thanks all.

Yes, the memory leak problem is still an issue in Domino 12.

BUT: There's a workaround. Set the following notes.ini to cache the agentloader objects and reuse them:

EnableJavaAgentCache=2

From SPR # BHUY8PRMKK:

“The Product Development Team had developed a possible fix that mitigates the issue but the fix was of medium risk and it was decided not to submit the fix. As an alternative they have come up with a workaround. Set the following notes.ini, this will cache the agentloader objects and reuse them.“

That's useful! Thanks! Any view on the OpenNTF domino API? Is that worth the install? – Adam Oct 10 '22 at 16:01

OpenNFT Domino API (ODA) does not solve the memory leak issue but yes, ODA is worth the install in general for Java on Domino. – Per Henrik Lausten Oct 10 '22 at 16:07
