maven-exec-plugin: Improve Exception Message PR

[Lukasz Cwik]

I created the following PR (https://github.com/mojohaus/exec-maven-plugin/pull/66) to unwrap the InvocationTargetException improving the error message which users get when their application fails. The PR had been sitting around for a couple of weeks and was wondering how to get traction to get it accepted and merged?

This PR removes the boilerplate found in the plugin output which preceeds the users stacktrace:

java.lang.reflect.InvocationTargetException
        at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
        at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)
        at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)
        at java.lang.reflect.Method.invoke(Method.java:498)
        at org.codehaus.mojo.exec.ExecJavaMojo$1.run(ExecJavaMojo.java:293)
        at java.lang.Thread.run(Thread.java:745)
... <Users Stack Trace> ...

making it just contain the stack trace from the users application.

This also removes null: InvocationTargetException: from the plugin output summary:

An exception occured while executing the Java class. null: InvocationTargetException: <Message from users exception>

thus making it:

An exception occured while executing the Java class. <Message from users exception>
