Re: Just realized that I probably have another memory leak in RPG calling Java

Are you set up for enabling garbage collection in general?

I assume so, since you say "another memory leak", but just in case, and also for the archives ...

The ILE RPG Programmer's Guide has a section that talks about enabling Java garbage collection. There's also a wiki page in the RPG Cafe that has all the code from that section of the manual along with a sample program. (2 zip files, one with a savlib save file, and one with the source.)

Here's the URL for the wiki page:

Here's a short URL for that: https://ibm.biz/BdxqxU

The sample program would be more interesting if it had also had a nested pair of beginObjGroup() and endObjGroup() in the loop.
