Description Eric Goff CLA 2007-03-29 15:09:56 EDT 
Build ID: I20070323-1616

Steps To Reproduce:
1. Try to edit snippet of code
2. eclipse freezes


More information:
Here was snippet:
public <T> foo<T> bar() ;

As I tried to change this to:
public <T extends fubar> foo<T> bar() ;

eclipse froze.  Was reproducible 100% of the time,
but I suspect only the context of my environment.

This *possibly* seemed to be related to "Open Type" being broken and doing weird things (I entred bug for that as well)

Please attach a stack dump.
Comment 2 Jerome Lanneluc CLA 2007-04-02 12:07:42 EDT 
Eric, any news on this one ? Were you able to take a thread dump (start eclipe with -vm <path to your jdk>\bin\java.exe, then press Ctrl+Break in the DOS console when the freeze occurs) ?
Comment 3 Eric Goff CLA 2007-04-02 12:43:18 EDT 
I did not realize someone wanted my input, sorry.
I will try a "kill -3" on it to get a stack trace.
Comment 4 Eric Goff CLA 2007-04-02 14:07:05 EDT 
After blowing away eclipse directory and starting again,
problem went away.

However, problem had not gone away after starting with eclipse -clean.

So problem sounds unreproducible at this time.

Thanks Eric. Please reopen if you see this again.
