When the name of a non-existant class is given to gij, the error given is far
too verbose:
$ gij Blah
Exception in thread "main" java.lang.NoClassDefFoundError: Blah
at gnu.java.lang.MainThread.run (MainThread.java:98)
Caused by: java.lang.ClassNotFoundException: Blah not found in
gnu.gcj.runtime.SystemClassLoader{urls=[file:./],
parent=gnu.gcj.runtime.VMClassLoader{urls=[core:/], parent=null}}
at java.net.URLClassLoader.findClass (URLClassLoader.java:923)
at java.lang.ClassLoader.loadClass (ClassLoader.java:309)
at java.lang.Class.forName (natClass.cc:88)
at gnu.java.lang.MainThread.run (MainThread.java:94)
This is a lot more information than the user needs. Compare this with Sun's VM:
$ java Blah
Exception in thread "main" java.lang.NoClassDefFoundError: Blah
We should not wrap the ClassNotFoundException in MainThread.run, and the stack
trace code should supress stack trace printing when main() has not yet been
called (or, at least, for this special case - when the exception is thrown from
MainThread.run).

Note that I made it more verbose then it was in the past on purpose.
But not for this case. See an example of a stacktrace were (most) of this
"extra" information is useful:
http://gcc.gnu.org/ml/java-patches/2005-q1/msg00337.html
This really helps when debugging strange reasons for your main class not wanting
to start correctly.
When cleaning this up be careful to at least keep the root cause and the
classloaders and search paths used. And when the root cause is some (chained)
ExceptionInInitializerError inside some super or interface class needed by the
main class you really want the stacktrace to track down why/what happened where.
