Description
The 1.4.2 version of javap prints signatures of certain methods incorrectly. The 1.4.1 and 1.5 versions of the tool function correctly.

To reproduce the problem, extract the attached jogl.jar (from http://jogl.dev.java.net) and run

javap -classpath jogl.jar net.java.games.jogl.GLU | grep gluProject

The incorrect output printed with the 1.4.2 javap is

    public abstract boolean gluProject(double,double,double,double[]);
    public abstract boolean gluProject(double,double,double,double[]);

The correct output printed with the 1.4.1 or 1.5 versions of javap is

    public abstract boolean gluProject(double, double, double, double[], double[], int[], double[], double[], double[]);
    public abstract boolean gluProject(double, double, double, double[], double[], int[], double[]);

This bug was reported by end users and is very confusing to them. The fix from the 1.5 workspace should be backported to a 1.4.2 update release.
