329522 - Use JNI's RegisterNatives in javaxpcomglue

Status: RESOLVED FIXED

(Core Graveyard :: Java to XPCOM Bridge, defect)

Description

[jhp (no longer active)]

JNI provides a RegisterNatives method which associates a given Java native method with a method implementation.  This is in contrast to explicitly exporting the method impls from the JNI library and then loading the library into Java.

Using RegisterNatives would make it easier to add Java native methods in the future, since we wouldn't need to worry about creating an exported dummy method in javaxpcomglue.  Also, it would remove the javaxpcomglue library as the go between when Java methods call into XPCOM and back.  That is, all calls into XPCOM from Java currently look like this:

  Java --> javaxpcomlgue  \
                           > JavaXPCOM (as part of libXUL)
  Java <-- javaxpcomglue  /

Using RegisterNatives, we can directly associate the Java methods with their implementations in the XUL library.

Use RegisterNatives.  Also allowed me to get rid of function ptr globals.
