Assigning to radim. Not sure where is the bug. Problem can be, that following
code runs in AWT:

...
at org.openide.awt.SwingBrowserImpl.setURL(SwingBrowserImpl.java:75)

at org.openide.awt.HtmlBrowser$1.run(HtmlBrowser.java:401)
...

It is not the ICEBrowser what grabs your AWTThread. It is JEditorPane from
Swing. Namely the implementation of setPage that read URL content from AWT thread.
Comment 4 _ rkubacki 2001-09-18 09:05:56 UTC 
One way how to fix this bug is to make browser window non-persistent.
Similarly if IDE display URLs in external browser they are not
reopened when IDE is restarted so can cancel deserialization of
internal browser too. 

Moreover the internal browser is not deserialized in current version
if we can't connect to URL. This handles cases when there was browser
showing executed/debugged JSP or servlet page.

this bug is not JDK 1.4 specific.  Radim's evaluation is right: the
root of trouble is JEditorPane.setPage(URL) which runs in AWT thread
and runs asynchronously.

javadoc of this method says you can make JEditorPane.setPage async by
calling setAsynchronousLoadPriority on the AbstractDocument associated
with the JEditorPane.  I fixed the bug by doing so iff the URL's
protocol is http or ftp, otherwise do it synchronously  (http and ftp
are the only two network protocols, JDK/NB understands).  There is a
cost attached with async loading of the URL (one more thread), so I
don't want to enable it in all cases

Resolved for 3.4.x or earlier, no new info since then -> closing.
