Comment 168 for bug 1572801

Davias, even though this bug report was originally about the other memory problem of using excessive memory as soon as it turns on, don't see the harm in helping with this java memory problem too since it doesn't look like Canonical is going to fix either one for 16.04 since it has existed so long and we are getting close to another LTS release in April. I had that java memory leak in lubuntu 16.04 for a minecraft server I left on all the time and the memory regularly maxed out regardless of java settings, there was even a thread about it last year somewhere on the Ubuntu forums where it was recommended I switch to a window manager instead of a desktop environment. Memory management was better with openbox on ubuntu without a desktop environment. The minecraft server we have is now on debian 9 without a desktop environment, and I let that run java all week long without the memory leak.

One of my kids now uses kubuntu 16.04 to play minecraft with Oracle Java and it is ok with kde. However java is not constantly running on kubuntu so I can't guarantee it won't have the memory leak after several days of constant java use all day long. So you can try kubuntu 16.04, or probably any ubuntu 14.04. I've switched my personal computer to debian 9 and haven't noticed that memory leak for java with debian either in kde, but once again this computer doesn't run java all the time.
