Description Jan Sievers CLA 2011-04-08 09:05:52 EDT 
Created attachment 192823 [details]
process explorer process hierarchy

I open the context menu on several projects to share them via git and eclipse hangs forever.
I see in the process explorer that eclipse.exe is waiting on bash.exe which in turn waits on which.exe (which seemingly never returns).

See VM stacktrace I obtained via jstack from the hanging process below.

Together with Christian Halstrick I was able to show that the problem is influenced by my PATH environment variable.

C:\Program Files\Windows Resource Kits\Tools\;c:\maketools\perl\bin;c:\maketools\bin;C:\PROGRA~1\SECUDE\SECUDE~1;C:\WINDOWS\system32;C:\WINDOWS;C:\WIN
DOWS\System32\Wbem;C:\Program Files\Common Files\OpSession\Shared;C:\Program Files\Common Files\OpSession\Viewer Shared;C:\Program Files\Symantec\pcAn
ywhere\;C:\Program Files\Perforce;c:\tools;C:\libs\apache-ant-1.7.1\bin;c:\Program Files\Support Tools\;C:\Program Files\Microsoft SQL Server\90\Tools
\binn\;C:\Program Files\Microsoft SQL Server\90\DTS\Binn\;C:\Program Files\Microsoft SQL Server\90\Tools\Binn\VSShell\Common7\IDE\;C:\libs\apache-mave
n-3.0.2\bin;c:\Program Files\putty;c:\tools\git\bin;c:\cygwin\bin;C:\Program Files\Windows Imaging\

If I reduce PATH to just C:\WINDOWS\system32;C:\WINDOWS, the problem does not occur.
