Although the JNI spec itself is not an open document I see no reason not to get feedback on this simple update.
Bug: https://bugs.openjdk.java.net/browse/JDK-6516521 --- Chapter 5: The Invocation API Creating the VM The JNICreateJavaVM() function loads and initializes a Java VM and returns a pointer to the JNI interface pointer. The thread that called JNICreateJavaVM() is considered to be the main thread. --- Proposed additional text: Note: Depending on the operating system, the primordial process thread may be subject to special handling that impacts its ability to function properly as a normal Java thread (such as having a limited stack size and being able to throw
StackOverflowError). It is strongly recommended that the primordial thread is not used to load the Java VM, but that a new thread is created just for that purpose. Thanks, David
