[tcljava-user] Getting a useful stack trace from a java exception returned from a method called in jacl

[Jared H. <ho...@mo...>]

Hi all,

   So I am using jacl in our java code a lot like glue to hold the
various pieces of java code together.  I write all of the simple stuff
in tcl and all of the stuff that needs to go fast goes into java.  So
anyway, I'm sometimes debugging java code by calling it in jacl.  My
question is, how do I get a useful stack trace out of a method I call
this way?  I've tried catching the TclException that gets called and
printing out it's stack trace, but it always ends at:

tcl.lang.ReflectException

   at tcl.lang.JavaInvoke.call(JavaInvoke.java:328)

   ...

 

I've looked in the code, and it looks like the call method is catching
the InvocationTargetException and wrapping it in a ReflectException.
This would be fine and I would just call "getThrowable" and print it's
stack trace if ReflectException was public.  Is there any reason this
class needs to not be public?    Is there maybe another way to get to
this?  I don't want to have to mess with wrapping every call in
"java::call" when I can simply put a java call in my code.
