java-1.4.2-gcj-compat provides (in the rpm sense) jaxp_parser_impl but does not provide the /usr/share/java/jaxp_parser_impl.jar alternative symlink. The relevant classes are found ok (they're in libgcj.jar) but the missing link causes JPackage applications that use "build-classpath jaxp_parser_impl" to emit error messages.
So the /usr/share/java/jaxp_parser_impl.jar alternative symlink should point to libgcj.jar?
Yeah, I guess, since it worked for all the other dummy jarfiles.
Should be fixed in java-1.4.2-gcj-compat-1.4.2.0-40jpp_30rh. Closing.
