"limitations of static linking." for the Cygwin/Ming port of gcj

Hi all:

First off I'd like to say it's great to have a compiler running without
all the Sun Microsystems/Oracle branding.

I'm running gcj version 3.4.4 on Cygwin 1.7.9 with java version 1.6

According to this message:
http://gcc.gnu.org/ml/java/2005-04/msg00050.html

and the correspondence, gcj has trouble with dynamic linking for the
regexp classes. But as of 2009:

September 22, 2009
GCJ support on Windows (Cygwin and MinGW) targets has been enhanced with
a number of bugfixes, and the option to build libgcj in DLL form for
dynamic runtime linking.

"dynamic runtime linking" which I understand can fix the exception has
been enabled. My question is when compiling code with the String.split()
method, I still get the error at runtime:

Exception in thread "main" java.lang.Error: Not implemented
     <<No stacktrace available>>

so how would I go about fixing this?
I'm new to cygwin and gcj but I've used linux command line for a little
over 2 years now.

Much appreciated.
Franklin
