I don't think there is in Fedora. I don't know about JPackage.
I'll check.

You could probably try changing the BuildRequires line on java-devel and
rebuild. With no target specified, it'll probably build whatever your
javac defaults to (which I thought was less than its version but
evidently not).
Doesn't work, because the build itself needs ant which doesn't run with Sun JDK5.
Unless I manually
install another ant and force it to the path.

I don't know. Maybe the targets that are required in your case aren't
used by any Fedora packages which build with gij?
Looks like that gij doesn't use xerces to provide jaxp services:
# alternatives --display jaxp_parser_impl
jaxp_parser_impl - status is manual.
link currently points to /usr/share/java/xerces-j2.jar
/usr/share/java/libgcj-4.4.4.jar - priority 20
/usr/share/java/xerces-j2.jar - priority 40
Current `best' version is /usr/share/java/xerces-j2.jar.
But running ant with gij and gcj yelds:
-------------------------------------------
XML Parser information
-------------------------------------------
XML Parser : org.apache.xerces.jaxp.SAXParserImpl
XML Parser Location: /usr/share/java/jaxp_parser_impl.jar
Namespace-aware parser : org.apache.xerces.jaxp.SAXParserImpl$JAXPSAXParser
Namespace-aware parser Location: /usr/share/java/jaxp_parser_impl.jar
Maybe gij finds it's own jaxp implementation in libgcj.jar before trying xerves, and
so ant works.
But I don't like the idea of making whatever jaxp parser comes in libgcj be the
system-wide default
for JDK 5. Or maybe gij and classpath provide for some JDK6 features, including the class
file
format.
