--- Comment #1 from Tim Funk <funk...@apache.org> 2009-11-05 11:49:49 UTC ---
I believe the NPE is this:
page.visit(errVisitor);
Which is caused by
JavacErrorDetail detail = ErrorDispatcher.createJavacError(
jspFrame.getMethodName(),
this.ctxt.getCompiler().getPageNodes(),
null,
javaLineNumber,
ctxt);
So one wonders ... why is this.ctxt.getCompiler().getPageNodes() null?
It could be that compilation is done in 2 passes. And the first pass is
validation. So if this fails - then getPageNodes would be null.
So the easy fix may be this (not sure if its the right fix)...
