I'm not sure it is related to the Java version at hand. What I suspect
to have been the culprit in your situation, is the architecture of the
Java installation you employed on your Windows machine.

32-bit applications on Windows can only use 2 GiB of virtual memory (or
3 GiB with the large address awareness flag set in the executable
image), and Java is quite liberal in its virtual memory usage…

Oracle recommends using a 32-bit Java under most conditions, even on a
64-bit Windows installation. On 64-bit Linux, you'll probably have had a
64-bit Java by default, on Windows, it might have been a 32-bit one.

If you can reproduce this on a 64-bit JVM (you can check the version and
architecture with the command `java -version'), please file a bug report.
