Comment 2 Dusan Balek 2010-03-11 10:44:02 UTC 
Seems like a JDK problem. AWT thread is blocked inside javax.swing.JComponent.scrollRectToVisible(...) call.
Comment 3 Antonin Nebuzelsky 2010-10-04 14:12:27 UTC 
See this very old JDK bug which seems to be still valid regardless all comments about some fix in jdk6.

Please evaluate if HTMLDocView could be changed to workaround the JDK bug. See the Evaluation part of the JDK bug report for possible help.
Comment 4 Dusan Balek 2010-11-04 16:19:29 UTC 
The evaluation part of the above mentioned JDK bug suggest to switch the
views used to display a wrapped JTextArea to ZoneView and ParagraphView.
I'm afraid that we don't want to write our own HTML renderer (since code completion uses standard HTML rendering mechanism from JDK - HTMLDocView is just a JEditorPane with HTMLEditorKit installed).
