We have a swing based Java application runs well under JDK 1.3. When we upgrade to JDK 1.4.2 recently, it can be compiled. When we run the application most parts worked well. But it took 100% CPU time when we tried open some screens. When I click the dropdowns in these screens, it did not disply properly.

Any thoughts? Experience?

Have you tried to profile your code? Any ideas where it might be sucking up some CPU time?

Are you using multiple threads at all?
