Comment 3 Milutin Kristofic 2012-06-05 13:02:16 UTC 
Keymap is waiting for a lock, which is slowed down by loading Jar file (in load actions). There is no space for improvement.
Comment 4 Marian Mirilovic 2012-06-05 13:04:19 UTC 
I would say, we have problem with loading jars .. especially on Wins ...
Comment 5 Jaroslav Tulach 2012-06-07 09:33:45 UTC 
If classloading is slow, then try to do it sooner than in AWT. There are various ways for an EditorKit to pre-load necessary data structures before it goes into "install" phase. For example XMLKit can implement Callable. Or editor can initialize getKeymap for all EditorKits.
