[Soot-list] [Paddle] No method void register(java.lang.Object) in class java.lang.ref.Finalizer

[Yao Qi]

Soot developers,

When I run Paddle(nightly build) on IBM JDK, I get such error,

I checked java.lang.ref.Finalizer in IBM JDK, and find that there is no
such method register(Object), while there is such method in SUN
JDK.  (This case could work on SUN JDK)

Can I replace 

protected final NumberedString sigRegister = Scene.v().getSubSigNumberer().
        findOrAdd( "void register(java.lang.Object)" );

by 

protected final NumberedString sigRegister = Scene.v().getSubSigNumberer().
        findOrAdd( "void runFinalization()" );

in soot.jimple.paddle.TradStaticCallBuilder?

Because, runFinalization() could be found in both SUN IDK and IBM JDK.

I am a newbie on Paddle and point-to analysis, and just want to make
this example run at first.  Not sure that this change brings problems 
to Paddle or not.  Any comments?  Thanks.

Best Regards
