gcj has an evil bug.  Sometimes, when it has an unresolved reference, it
reports a ClassNotFoundException for the referring class, not the
referred.  So, you now need to

jcf-dump -v -classpath /usr/share/java/eclipse-ecj-3.5.1.jar org.eclipse.jdt.internal.compiler.Compiler

and have a look at the class references in the constant pool.
