I've never seen that kind of behavior after using the debugger for more
than 10 years. A prerequisite for fixing a problem is typically being
able to reproduce the problem in the first place, so if no one ever
provides a way to reproduce the problem and the developers have no
theory that they might be able to use to reproduce it themselves, it's
highly unlikely that anything will be done (because it's impossible).
I.e., the title itself qualifies the problem with "in some cases", but
it doesn't illustrate the cases in a way that allows another developer
to reproduce it.

Not enough information to consider, but couple of general points
1) Debugging turns off the JIT so no speed ups by doing just in time compiling
2) Sometimes a limited data set can still product the same result (bug hit). might try using only part of the data.
3) find ways to optimize that section of code before debugging. it will be faster in debug and faster in actual use.
4) if data set gets buffered into structures in storage, are you running on large enough environment to avoid lots of swapping.
5) if using remote jvm connection for debug. try and move the eclipse and debug environment onto same machine to avoid costly network delays.
