Hi,I use emacs22.1,jde2.3.5.1,cedet 1.0pre3,elib-1.0 to develop java
application.
I set the break point and press C-c C-v C-d to start debug.(using jdb)
It stop at the break point,but when I press C-c C-a C-s(step over),
It can't work any more,The step over,step in,step out,continue menu
became disable status.
I tried at both linux and window,It have the same problem.
When I set jde-debugger to jdebug,Perhaps It works OK,But slowly.

Does it mean jdee can't fully support emacs22 and
Is there any way to solve this problem?
