IntelliJ 9.0.1 - Multiple fatal crashes

I've been experiencing IDE crashes at least once a week with v9.x; I've never had this happen before and I've been using it since v5.  I have yet to discover any common themes to the crashes, it's just, one moment I'm editing, the next the window has closed and I've lost all my changes since the last auto-save.

It's the "lost all my changes" (and the "at least once a week") part that's really starting to wear homicidally-thin.  I haven't sweared so much in years.

Additionally, for some reason the IDEA64.EXE that allows IntelliJ to work with the 64-bit JVM no longer works (IDE loads up, then hangs when indexing).

I've attached the thread dumps if it's any help.


And once again today... crash, lost files.  This time no logs in the thread dump directories.  Happily editing code in the editor (java code if it makes any difference), minding my own business, then BLAMO!  I'm looking at my desktop.

The one thing I do see in the main idea.log file is tons of @NotNull exceptions:

aemon.impl.PassExecutorService - @NotNull method com/intellij/psi/impl/light/LightVariableBase.getName must not return null
java.lang.IllegalStateException: @NotNull method com/intellij/psi/impl/light/LightVariableBase.getName must not return null


Are you running under Sun JVM 1.6.0_u18? If so, it's a known bug, fixed in u19. If possible you should upgrade. If not, add this to your idea.vmoptions file:

Are you running under Sun JVM 1.6.0_u18?

I am, actually.  I'll upgrade and update the thread with my findings.  Thank you!


No luck getting the 64-bit JDK working.  IntelliJ hangs while updating indexes and trying to redraw the left-side PROJECT view.  Either that, or it's indexing EXTREMELY slowly.  And the RAM usage went to over a gig.

Haven't had time to update the 32-bit JDK on my system (was really hoping this would fix it), but hopefully that at least stop the random crashes & subsequent data loss.
