Last night, I was working in Eclipse Juno when it stopped responding. It's been doing this ever since; if I try to modify code or run it, it will stop responding for a few seconds.

In Task Manager, it shows several instances of javaw.exe running and that my CPU is at 100%. However, seeing as my computer is still running, I doubt that is actually the case. Nonetheless, these files worry me and I don't know if they should be deleted or not.

I tried increasing the memory of the classes I'm working on (Eclipse "javaw.exe" High CPU usage -> How to increase application heap size in Eclipse?) but it didn't help.

I'm don't know to much about the inner workings of Eclipse so please bear with me.

    Have you tried the old cure-all for misbehaving Windows programs: reboot? – Ted Hopp Jan 02 '15 at 18:37
  • Kinda sounds like malware (besides Eclipse, I mean). When I run Eclipse Luna for C++ dev, I see at most two instances of javaw.exe with at most a few percent (plus the jusched.exe). – dwn Jan 02 '15 at 19:37
  • What did you increase the heap size to? How much free memory do you have before you start Eclipse? – Jeremy Stein Jan 02 '15 at 19:38
  • I put in -Xmx2048m for VM arguments, as suggested in the heap size question. I'll run a scan, but I don't think I have malware. – JeffH Jan 02 '15 at 19:56
  • I ran a full system scan and everything was resolved. The problems persist. – JeffH Jan 02 '15 at 21:00
  • If you are developing in C/C++ and are not invested in using Eclipse, you could try SublimeText3 (with add-on packages) or Qt Creator. – dwn Jan 03 '15 at 04:22
