X 1.0rc1: Windows 7 64: Sudden crash with a long running script using observe()

******** possible reason: observe() buggy in rc1 (fixed in rc2)
----------------------------------------------------------------

I'm using the Sikuli X 1.0rc1.

The script runs more than 5 mins.

After a while, the 'java.exe' suddenly dies with no apparent reason leaving a log file as below:

#
# A fatal error has been detected by the Java Runtime Environment:
