This had already been fixed in Octave-Forge svn in late June:

(http://sourceforge.net/p/octave/code/10706/tree//trunk/octave-forge/extra/java/inst/dlgtest.m?diff=505e333171b75b10eb655d97:10705)

Note: Sourceforge SVN currently has problems and is very slow.

AFAICS JWE has definitely imported a Java pkg version from before June,
2012, and I think I know what might have deceived him into assuming it was
up-to-date.
I'll investigate the next days/week what changes/patches to the late Java
package SVN have to be re-applied to core Octave; I still have my own
up-to-date svn repo on my dev box at home. (I made the last two or three
Java package releases.)

IOW, please don't commit patches/changesets to the Java files, except the
autotools, until I've sorted it out.

See bug #37834

Thanks,

Philip
