D's GC needed to stop the world, which meant it would have to know what threads were running. You can never be sure whether your D library function is being called from a thread you've known or whether the Java runtime (or other user code) just decided to start another thread.
Interesting... you know, maybe D's GC should formally expose a mutex that you can synchronize on for when it is running. So you can cooperatively do this in the jni bridge or something. Might be worth considering.
I've heard stories about similar things happening with C#.
