Preventing Java processes from getting stuck running?

I have come across this issue many times now and every now and then after running my process over and over again as I edit I come across that it will start leaving java processes in the task manager. This can cause error if your trying to run it again and the last Java process didn't close properly.

Is there a way to avoid this or is this just a bug?


  • It might be of interest to mention what system you use, what version of Processing (and perhaps of Java) you use, etc.

    Personally, I use Processing for years (on Windows, XP and 7, always in 32-bit mode) and never had this issue.

  • I have a Windows 7 64bit and i use Processing 2.2.1.

    Just throwing that out there, as long as I take it slow the issue doesn't occur normally.
