No support for saxon-ee with xslt-debugger.

I have put on my jre/lib/ext the jar for saxon-ee.jar (for use extensible functions, reflective calls to java) but when i try to debug i got this error: 

java.lang.UnsupportedOperationException: Unsupported Transformer: net.sf.saxon.jaxp.TransformerImpl
at org.intellij.plugins.xsltDebugger.rt.engine.local.LocalDebugger.prepareTransformer(LocalDebugger.java:93)
at org.intellij.plugins.xsltDebugger.rt.engine.local.LocalDebugger.<init>(LocalDebugger.java:46)
at org.intellij.plugins.xsltDebugger.rt.engine.remote.DebuggerServer$1.<init>(DebuggerServer.java:50)

How is it possible that xslt-debugger only work with saxon-he that doesn't supports reflective calls ??

Is anyway to debug with intellij a xslt with reflective calls ? 

Thank you
