Hi,
On Windows with JDK6, the following tests fail:
I see the rmi tests on linux+the latest jdk6 too.

Well, there's our problem.
Actually, this whole area was trouble, look at this bug. that the
XNewRmic compiler points to
http://issues.apache.org/bugzilla/show_bug.cgi?id=38732
and, from the command line, xnewForked works

1. the testXnew should be skipped for Java6; don't know about
successors. But ignore this particular failure as it is something going
in rmic that we can't handle.

Now, this is fun. This routine works from the command line.
But under junit,

cannot be cast to org.apache.xerces.xni.parser.XMLParserConfiguration

Hypothesis: running -Xnew compiler in Java6 unforked screws up Ant for
the rest of the life of the process, by fiddling with the XML factories.
Whoever wrote that code made some assumptions about running in a self
contained process that doesnt hold.
Here's some options
1. Turn off testXNew
-stops rmic failing, stops the followon tests failing. hides any
problems with rmic on java
2 patch SunRmic to see the -Xnew parameter, and fail the build, tell
the user they need to fork the jvm
-changes test outcome on java6+, but leads to a better end user experience
