This is because we've compiled and linked Eclipse with libgcj4's .so but
you're running with gij from the 3.4.x package (which is linked against
libgcj 3.4.x's .so). You just need to set your alternatives to point to
java-1.4.2-gcj4-compat and -devel. See blow:
Even after setting the alternative java and javac, I still see the
RenderedImage gcj failure.

Actually, I set it to point to /usr/bin/java so that you can run it with a
proprietary JVM if you want. Are you familiar with the alternatives system
at all? Install java-1.4.2-gcj4-compat (and -devel), and you'll have a
setup similar to a traditional JVM (like any JPackage-style RPM, that is)
with /usr/bin/java, /usr/bin/javac, etc. but built around gcj/gij and ecj
(the Eclipse java compiler). Thus, when running Eclipse we want it to run
with gij. Make sure you set your alternative to java-gcj4-compat and
you'll be set:
su - -c "update-alternatives --set java \
/usr/lib/jvm/jre-1.4.2-gcj4/bin/java"
su - -c "update-alternatives --set javac \
/usr/lib/jvm/java-1.4.2-gcj4/bin/javac"

Reporting bugs that occur with gcj and do not occur with a proprietary JVM
(or at least you don't expect them to) helps even if you don't know where
in libgcj/gcj/gij the problem is occurring.
Thanks,

Now using the compat jvm, I've walked in a circle.
