Description gc 2004-11-18 11:17:06 UTC 
Very rarely, following exception is being thrown
when used with J2ME modules.  The J2ME code that
instigates the problem is: 

String
docText=document.getText(0,document.getLength()); 

which i don't think should be a problem.

Comment 1 Miloslav Metelka 2007-03-27 12:24:25 UTC 
This is caused by a missing document read-lock from j2me code before calling
doc.getText(). Reassigning to mobility.
Comment 2 Adam Sotona 2007-05-21 16:08:56 UTC 
The implementation of editor support in Mobility has changed significantly.
I havent seen the exception in 6.0. 
Closing as WORKSFORME, please reopen if occures again.
