I believe this code is there since ever. The error during the restore on "inconsistent" workspace state seem to affect startup in a bad way. See also bug 132220.
Just as a quick&dirty work-around: 1) is there a command line paramater to tell eclipse no to attempt the recovery of the crash-corrupted files that might still lie around after the last crash of my old eclipse.mars ? 2) if not, is there an easy manual way to "rm -rf" some directory tree where the corrupted files are lieing around ==> once they are gone, perhaps my newest eclipse will start again ? Many thanks in advance! original subject. <<Latest jee-oxygen refuses to start: An error has occurred. See the log file ... workspace/.metadata/.log>>

3) at least suggest to rename the .snap in the GUI as per Bug 520753 comment 1
(In reply to Ralf Hauser from comment #4) > 3) at least suggest to rename the .snap in the GUI as per Bug 520753 comment > 1 I wonder if we should guard Workspace.startup code from exceptions and instead of the dumb crash open a dialog: "Workspace data seem to be corrupted. Do you want to recover and restart? With two choices: "recover" and "exit". On recover we would try to do some cleanup work (rename snap file, whatever it is). WDYT?
This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. As such, we're closing this bug. If you have further information on the current state of the bug, please add it and reopen this bug. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant. -- The automated Eclipse Genie.
