Description Marek Fukala 2007-04-23 15:52:09 UTC 
The MyFirstDrawLayer.updateContext() method is called from the DrawEngine when
painting  the document and is very very slow -calls to FileSystems, then parses
the obtained data, simply no caching at all. 

Scrolling in the document is very very slow because of this.

Comment 1 Marek Fukala 2007-04-23 15:53:16 UTC 
To reproduce open a big html or jsp file for example from issue #101132 and try
to scroll over it.
Comment 2 Daniel Prusa 2007-04-24 14:09:20 UTC 
Fixed, bundle not accessed at all now.
