Description of problem:
In rawhide, I cannot build Eclipse with java-1.5.0-gcj as my alternative, but I
can with IcedTea as my alternative.

Version-Release number of selected component (if applicable):
libgcj-4.3.0-0.11.i386
java-1.5.0-gcj-1.5.0.0-19.fc9.i386

How reproducible:
Always

Steps to Reproduce:
(on a rawhide box)
1. cvs -d:pserver:anonymous.org:/cvs/pkgs co eclipse
2. cd eclipse/devel
3. make <your arch>
  
Actual results:
Build fails with gij exiting with a code of 13.

Expected results:
Build finishes successfully.

Additional info:
The actual failure is coming from this line:

java -cp
eclipse/devel/eclipse-3.3.1.1/eclipse/plugins/org.eclipse.equinox.launcher_1.0.1.R33x_v20070828.jar
-Duser.home=eclipse/devel/eclipse-3.3.1.1/home org.eclipse.core.launcher.Main
-debug -consolelog -application org.eclipse.ant.core.antRunner -Dtype=plugin

-DsourceDirectory=eclipse/devel/eclipse-3.3.1.1/equinox-incubator
-DbaseLocation=eclipse/devel/eclipse-3.3.1.1/eclipse
-Dbuilder=eclipse/devel/eclipse-3.3.1.1/eclipse/plugins/org.eclipse.pde.build_3.3.2.R331_v20071019/templates/package-build
-f
eclipse-3.3.1.1/eclipse/plugins/org.eclipse.pde.build_3.3.2.R331_v20071019/scripts/build.xml

If your alternative points to gij, this fails.  Pointing it to IcedTea (at least
on i386) makes it work.  Careful with the paths in the above snippet.
