The Websphere Studio 5.1.1 documentation describes the "Drop to frame" feature:
---
Context menu: Drop to Frame
This command lets you drop back and reenter a specified stack frame. This feature is similar to "running backwards" and restarting your program part-way through.
To drop back and reenter a specified stack frame, select the stack frame that you want to "drop" to, and select Drop to Frame from the context menu.
Some caveats apply to this feature:
You cannot drop past a native method on the stack.
Global data are unaffected and will retain their current values. For example, a static vector containing elements will not be cleared.
Note: This command is only enabled if the underlying VM supports this feature.

I using the Websphere 4.0
Test Environment. I'd like to be able
to use the "Drop to frame" feature while debugging a 4.0 application.
