>Description:
With the addition of dynamic loading for classes
(and uncommenting of some classloader code), statically
linked gcj applications which use Class.forName will
encounter circularity problems.
The basic problem is that the default ClassLoader is
a URL ClassLoader, which itself uses Class.forName to
find the correct protocol handler. Since forName tries
to create the system ClassLoader if it doesn't already
exist, and since with static linking the "file" URL
handler won't be linked in automatically (since nothing
explicitly references it), circularity results.
A workaround is to explicitly require the file URL
handler to be linked in (eg, using -u)
