I believe Guy verified that on Windows.
I’m not sure why Linux lightweight processes (LWP) would make a difference in this case. But as these behaviors are not specified no where, and are prone to be OS and JVM vendor and version depended, anything goes. Better not count on it.

We need some clear specifications from the JCP on overall JVM behavior in case of OOME.

Hi Guy,

thanks for checking the thread thing – it would be nice to know which platform you tested on, as different platforms may implement threading differently. On linux, I believe, threads are processes, unlike windows.

Can we assume you used windows from the icons on your post?

Thanks for the great article.
I’ve wrote a simple code that generates 2 threads were one of them created out of memory error – and the other thread kept working.
I’ve validate this on both IBM and SUN JVM.
So the conclusion is that the JVM does not terminate when OOME occurs.
