Ugh ... Linux emulator support for Java has been broken for several years.
I think it got sick somewhere between FreeBSD release 4.3 and 4.6.2.
I used to think that I must have installed the Java runtime incorrectly
but gradually became convinced the problem was in the Linux emulator.
I posted a question about the problem to a couple of FreeBSD mailing
lists and got no response.  I asked a dozen or so other FreeBSD users
if they had noticed this problem and not one of them would admit that
they used the JRE on FreeBSD (or the Linux Netscape which may be the
biggest JRE application) or that they cared one way or another.

I suspect that the FreeBSD Linux emulator has gotten a couple of
years out of date.  I think this is important but I can't complain
since I am in no position to maintain it myself.
