Sun's didn't have this problem. (Disclaimer: this was a year and some change ago, so this may be fixed by now.) 2) If you can find all the right settings to tweak (I'll see if I can dig up the documentation for this), the IBM JVM + Eclipse will run faster than the Sun JVM + Eclipse. Admittedly the difference isn't *that* huge, but if you're in Eclipse all day it can be a nice thing to have. 3) I found IBM's JVM to be less stable. Granted, this may have been trying to mix and match and use both, but I still think that Sun's seemed to be more reliable.
