EXTRA RELEVANT SYSTEM CONFIGURATION :

A DESCRIPTION OF THE PROBLEM :
When I run the test below on windows/jdk1.3.1 ,nothing
happened. Same on Solaris 2.8. But when I run it on linux/jdk1.3.1/
1.4.0 /1.4.1, it crashed with OutOfMemoryError.
However, it seems that using the -Xincgc flag prevents the Error
from occuring.
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
run the program on linux with any version of j2sdk for
about more than 10 minutes, then you might see
OutOfMemoryError. I am not quite sure if it is a bug or I
misunderstand the spec.
EXPECTED VERSUS ACTUAL BEHAVIOR :
OutOfMemoryError.
ERROR MESSAGES/STACK TRACES THAT OCCUR :
No stacktrace available.
REPRODUCIBILITY :
This bug can be reproduced always.
