I accidentally forced myself to move from Netbeans 5.5.1 to Netbeans 6 M10. I don't know if this is normal, but Netbeans has been running now for a few hours and the task manager is showing java.exe using almost 400Mb! My project isn't large by any stretch of the imagination; there might be about 30 classes, but they're mostly small with maybe 3 Swing derived classes. I can force the Java garbage collector to kick in, but that doesn't reduce the overall consumption. Scary! If I sit and watch Netbean's memory meter, it slowly rises by 100k every few seconds.
