[platform-debug-dev] Debugging issues in eclipse

[Matt.Gregory@xxxxxxxxx]

I have just switched to Eclipse and I am already stumped by my first
problem...

I am developing an applet which must be able to run under JDK 1.1.8 (for IE
standard compatability) so I have the project configured to compile with
JDK 1.1.8 by default.  The older JDK is horrible at debugging however so I
have been using JDK 1.4.1 to do the actual debugging.  No matter what I do,
I always get the following exception when my applet attempts to start a
thread to read file content from a stream from eclipse, but only in JDK
1.4.1:

java.security.AccessControlException: access denied

The same code initalizing the thread works outside of eclipse in both the
Mozilla and Internet Explorer VMs, as well as in JBuilder and from the
command line.  It also works fine in JDK 1.1.8 under eclipse when I simply
run, but my goal is to debug.

Again, I would like to point out that the default JDK is 1.1.8 (the one I'm
using to compile) but that I am running the compiled library with JDK 1.4.1
and attempting to debug it with 1.4.1 as well

My code intersects with the error at the line marked with the -> and looks
like this:
****code****
    if(engine == null) {
      engine = new Thread(this);
      engine.start();
    }
****code****
(the FileReaderFrame is a scrollbar frame which reads from a stream and
updates itself... it extends Runnable).
