Using JDK1.4.0 with Jswat

Dear all,

This is a quick note to anyone that has not managed to get jswat to work
with jdk1.4.x using win32 on NT4.

I was originally getting a slew of errors, originating from
sun.awt.windows.Win32DDRenderer.doFillRectDD(Native Method). I tried a
couple of versions of jswat - 2.5, 2.6 and 1.5. Each of them gave the same
error, which suggested that it was down to 1.4. I tried it with 1.3 and it
worked fine. I then looked on Google groups and found that there is an extra
switch that you can put in that turns off the win32 DirectX stuff - it seems
that there is a bug in 1.4 (I'm currently using 1.4.1-beta-b14) that means
it's not compatible with other programs that are using DirectX.

The switch is:

-Dsun.java2d.noddraw=true

So now my startup line is:

javaw -Dsun.java2d.noddraw=true -jar "c:\program files\jswat\jswat2.jar"

I hope that helps some people out that were keen to use the hotswap
facility - Nathan, it works a treat!
