java submissions always exceed memory limit

[papagiorgio]

When I add a java assignment as a teacher and submit it as a student, I always get "Memory-Limit Exceed", even with the most basic "hello world" program. When I submit the same program to ideone directly it reports a memory usage of around 240MB. Although when adding the assignment I can only choose the maximum memory usage to be between 1MB and 64MB. Is there any way I can fix this, or am I doing anything wrong? This seems to be an issue with java programs. I made another assignment and can submit a c-program for example and get it accepted without any problems.

I hope this is the right place for such a question, I came here through the "Bug reports, feature requests, help wanted and other issues" link in readme.md. Any help is highly appreciated =)

240MB? It is hard to believe that.

You can set the upper limit at Settings block->site admin->plugins->local->onlinejudge

Wow...thanks for the quick reply thumbsup

Yes, that helped a lot, after I increased the limit to 256MB, the submission got accepted right away.

I know, I couldn't really believe it myself. But you can check it yourself: go to ideone, select java, just click "enter template" above the editor and submit the bare template. It'll come back with a memory usage of around 245632 kB which is roughly 240MB.

Thanks for the feedback, so that I can close this issue confidently.

I do believe what you said. The only thing that is unbelievable is the expansion of java. The default 64MB limit did work several years ago.
