You can't mix and match libc_r, libkse, and libthr.  One and
only one library can be used.  Once you start bringing other
libraries into Java, like graphics which can bring in a
threads library, you have to be sure that all thread
libraries are the same.

In short, you have to use /etc/libmap.conf to globally
map libc_r to libkse in order to get the JDK to work
with libkse.

Now reverse the map so that libc_r is mapped to libkse.
