[PATCH] null params in extensions

[Kelly Campbell <ca...@channelpoint.com>]

I ran into a bug with handling of null args to java extensions. Here's an
example of what caused the errors:

<xsl:param name="foo">foo</xsl:param>
<xsl:variable name="bar" select="my-pkg-ext:Foo.new($foo)"/>

This type of case works fine when the param isn't overriden, but when I set
the param named foo on the Transformer to null from within some code,
MethodResolver.scoreMatch throws a NullPointerException. A patch which fixes
these problems is attached.

Thanks, Kelly --

I'll have a look at this and commit the change.  Can you enter this into
bugzilla?

Thanks for reporting and fixing this problem,
