and
Windows XP Home Edition

A DESCRIPTION OF THE PROBLEM :
When running the programm (drawing the GeneralPath) a segmentation fault on linux happens.

on windows a strange application error occurs (possibly due to a buffer overflow: windows opens up a dialog, claiming titled "java.exe" and something like there is no media in drive "/device/harddisk1/DR5" after pressing cancel and or retry multiple times - the jvm crashes.

attached is the logfile from the linux box

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
run the attached program - on linux it will crash immediately, on windows you might be presented a strange dialog - after multiple clicks on retry or cancel the program crashes too.

EXPECTED VERSUS ACTUAL BEHAVIOR :
expected: a nice GeneralPath
actual: a hot spot error

CUSTOMER SUBMITTED WORKAROUND :
this does not seem to happen if anti aliasing is turned off - at least not on my machine with the given GeneralPath, also slight changes in the coordinates of the GeneralPath object seem to avoid the crash
