DartEditor froze

[floitschG]

My DartEditor just froze on me after I initiated a code-completion.
I used jstack to recover the stacks (see attached files).

And another freeze with some other stacktraces (jstack3 and jstack4).

Just realized that one of each stacktrace could be completely unrelated (c1visualizer). Since I'm not sure if that's the case I will leave them attached to this report.

Do you know (or can you find out from the "About Dart Editor" menu item) which build of the editor you're using?

Were there any errors reported in the log file (inside the workspace/.metadata directory in the editor's install directory)? If so, could you attach them to this issue? Thanks!

Added Accepted label.

build 1698
attached the log files.

There are lots of interesting bugs reported in the log files (thank you!), but none of them appear to explain the problem you're seeing. I have just committed a CL (1724) that should help us get more information. If you can, please download that or some later build, delete the log files, and then send us the new log files if you should happen to see it again.

I can cause the editor to lockup at will in the Linux continuous build (1735) and Linux runtime workbench, and nothing shows up in the log. This lockup does not seem to occur in the Linux integration build (1584) or in either continuous or integration builds on Mac. To recreate in Linux...

* Launch editor first first time (no workspace)

• Create new application
• Add new line in run method
• Save
• Immediately type something then ctrl-space for code completion
• Editor locks up

When I do this from a runtime workbench, I find (see threads below)...

* there is one element in the indexer queue

• the UI thread is waiting for that one element to be indexed
• there does not seem to be any background thread indexing elements on the queue

I believe that this should be fixed by http://codereview.chromium.org/8639005/.
