return the same Java object, both for efficiency and so that the '=='
operator works as expected in Java when comparing two JSObjects.
However, it is not possible to hold a reference to a Java object without
inhibiting GC of that object, at least not in a way that is portable
to all vendor's JVMs, i.e. a weak reference. So, for now, JSObject identity
is broken.
means that we had to switch from using NSPR hash tables to a private version.
The new jsj_hash.c file is derived from plhash.c, but it provides for an additional
argument to be passed to the hash key comparison function. This capability
is used to pass in the JNIEnv pointer.
On shutdown, LiveConnect now removes all references to Java objects and classes,
so that the JVM might be able to GC them.
This new vendor-neutral version of LiveConnect is designed to replace the older
one in the js/jsj directory, which only works with the Netscape JVM. It is part
of the OJI initiative.
