XSLT Debugger SecurityException Signing Problems

Hi,

I'm trying to get the XSLT Debugger up and running. I am able to execute regular runs but unfortunately I haven't been able to successfully run the debugger in XSLT 2.0.

It's giving me the following exception:

Exception in thread "main" java.lang.SecurityException: Signers of 'net.sf.saxon.trans.XPathException' do not match signers of other classes in package

I've tried setting the VM Arguments to Saxon and Xalan: it'll run but in XSLT 1.0, and throw an exception at the first XSLT 2.0 function. I've also tried multiple versions of the Saxon jars, which are either incompatible or throw this exception.

Any help would be greatly appreciated, thanks!
