I often (cause unknown) have two problems with the debugger:
1) It loads the CPU 100% and the entire system becomes unresponsible for
several seconds to minutes
2) opening tree items in the debugger takes seconds ("Collecting data" or
something is printed in light gray, it seems to call each object's
toString() method. But even if so I don't know why it is so slow).
System is a 3GHz Pentium IV on XP an JDK 1.4 / 1.5.
