It's very hard to say.  Have a look in libgcj.jar:

 jcf-dump -classpath /home/aph/gcc/gcc-4_4-branch/install/share/java/libgcj-4.4.1.jar java.lang.String

You should see:

Method name:"format" public static varargs Descriptor: (java.lang.String,java.lang.Object[])java.lang.String

Make sure you're using the same libgcj.jar as the compiler.
