Our source licensee has hit a crash in a particular scenario when the
memory limit is reached and they are trying to create an array using
NewIntArray(). In this case NewIntArray() returns NULL. As we don’t have the

This issue is seen with JDK 5.0 , 6.0 & 7.0 too . From the suggested
change below, our understanding is that this is platform independent. The
following are the suggested changes:

--- FileSystemPreferences.c (revision 6511)
+++ FileSystemPreferences.c (working copy)
