throwing static exceptions sometimes VERY slow!

[Wieland, Jacob]

Hi,


I am observing a very strange behavior.


In our generated code (due to various reasons I won't go into here unless I have to, but trust me, they are legit), we throw static exceptions for control flow purposes, This seems to work fine and without performance loss most of the time. However, we are observing now that every few seconds, a throw sometimes takes up between 1,5 and 2.5 seconds! (in contrast to the normal almost non-measurable time).


Update: it seems that the observed behavior was kind of related with some extraneous circumstances (the computer seems to have been more lagged than usual at that point). By now, I can only observe throws that take up to 20 milliseconds (which opposed to the normal time still seems slow).


It does not seem to be GC related, the only idea that I have is the jitter.


So, my question is. Is this a known (and for some strange reason maybe even accepted) behavior or is this a bug that I should file with Oracle (or you guys).
