I am having this problem for some weeks now, eclipse starts with splash screen, loads plugins, workbench etc, UI opens and closes immediately. I have tried everything possible, there are no log files generated in .metadata. Problem started with Helios then I installed Juno but still its same. I have tried installing JDK 1.6 , 1.7 again but didnt work as well.
What all i have tried :
1) All the possible changes in eclipse.ini, perm size, -vm argument 2) console with -clean and -clonsoleLog -debug option, no errors , problem persists 3) system restore to a previous date when Helios was working correctly
Please help me. Shashank
