Comment 2 Steve Northover 2006-03-13 13:12:41 EST

I hang about 2-5 times a day for around 30-60 seconds each time.  The menu bar goes white and the app becomes unresponsive (this is what Windows does when an appication stops dispatching events).  I run with the console.  When I hit Ctrl+Break, I am always in java.util.zip.ZipFile.  Most of the time, the UI is accessing it, but other times, there are two worker threads there.

I will paste the stacks I am seeing in this bug report.

Comment 3 Steve Northover 2006-03-13 13:22:41 EST

Here is all of the stack I got (I'll make my console buffer bigger).  I got this when Eclipse was starting up and it was trying to restore my hierarchical class view:

Comment 4 Steve Northover 2006-03-13 13:35:36 EST

Next time I'm going to edit out the sleeping workers so the there is less stack to read.

Comment 5 Martin Aeschlimann 2006-03-21 01:45:00 EST

Markus, can you have a look?

I think enablement for copy should not be necessary at all: copy should always be enabled if we have a element selected as we always copy the file name.

Comment 6 Markus Keller 2006-03-24 07:45:29 EST

I removed the unnecessary binary (bug 129922) and source availability checks for IJavaElements on Copy. I refrained from enabling Copy all the time, since there are situations where we wouldn't know what to do on Paste then (e.g. when copying a parent and its child, or a project and a file).

Fixed in HEAD.

Comment 7 Martin Aeschlimann 2006-03-24 13:03:23 EST

It should always be possible to do a textual paste, e.g. past the file names into a text editor.

Comment 8 Markus Keller 2006-03-24 13:51:36 EST

Filed enhancement bug 133192 for comment 7.
