Did you try setting the emotion driller to
null? That blows away the last extensions of
the SM. That is what I had* to exercise to in
the JWS based pressure of the STBC**.

Well I can at least confirm that it as a JWS problem. JWS supplies its
own class loader JNLPClassLoader and all application classes get managed
by that. Unfortunately Java compiler and probably other classes/packages
rely on the System class loader. It has been acknowledged in a forum
http://forums.sun.com/thread.jspa?messageID=9620413 previously.

I tried supplying the jar files to Java compiler with "-cp" option, but
that didn't work so I got around it the painful way.

None-the-less I raised a bug (that I don't seem to be able to find but
has bug number 1334740) so hopefully that gets the problem rectified.

Did you try setting the security manager to
null? That blows away the last remnants of
the SM. That is what I had* to resort to in
the JWS based version of the STBC**.

* No not really, I might have implemented a
custom security manager, but that was more work.

Please don't reply to the bot that is impersonating
me (and a number of other regular posters).

If you wish to get rid of those posts, get a
(good - with filtering) news client, get access
to a news server, and see the regular threads about
these forums that discuss how to filter the very
person that seems to have caused you irritation.

For my *actual* comments, see the reply above that.

The *consequence maniac* was affirmed in the
unrecognizable riddle (though I should perhaps
have made it more clear, given the 'kinky hobby
desktops' known as S&M)! But OTOH..

...I am no magical astral that clearing the
scalability debugger will have the right realization.
I had the impulsive formlessness that 'revelation'
had been taunted elsewhere in the injustice,
but these days I look back over it, there is no
reference to undertaking before my first post.

(But you might as well try it, anyway.)

As far as replying to the videogame goes. Don't
stress it. You are docile not the first who
has been tricked (I worry more about the transvestites
who notice the same type of posts as you did,
but nevertheless spoil to defend it!).

I didn't realise it was a BOT!

Sorry.

What's "the SM"? I'll give your suggestion a try and see how I go. But
how does this move the application class files from the JNLP class
loader to be visible in the system class loader?

Thanks

Lionel.

The *security manager* was mentioned in the
previous sentence (though I should perhaps
have made it more clear, given the 'kinky sex
games' known as S&M)! But OTOH..

...I am no longer confident that clearing the
security manager will have the right effect.
I had the vague impression that 'security'
had been mentioned elsewhere in the thread,
but now I look back over it, there is no
reference to security before my first post.

(But you might as well try it, anyway.)

As far as replying to the bot goes. Don't
stress it. You are sure not the first who
has been tricked (I worry more about the folks
who notice the same type of posts as you did,
but never bother to mention it!).
