The debugger is very slow when debugging under JDK 1.3 in JBuilder 3.5. How can I improve performance?

Answer:

Although debugging JDK 1.3 in JBuilder 3.5 is not offically supported, you can try to improve the performance of the debugger by doing the following steps:

1. Go to Project | Project Properties.
2. Click on the "Run" tab.
3. Add "-classic" in the VM parameters field.

This will cause the VM to not use the HotSpot compiler.
