18 seconds is a really long time -> P2.

AWT thread is blocked by class-loading. It seems to be an unfortunate consequence of JDK bug 6826789. SecureClassLoader is using URL.equals() and URL.hashCode() that can be very slow because they perform DNS lookup. See http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6826789 for details.

I doubt that we can do anything with that since we cannot avoid class loading from event-dispatch thread.

This bug is now also tracked on the JavaFX side as http://javafx-jira.kenai.com/browse/RT-22458.

But since we are using the embedded server now in the IDE, rather than opening the files directly from the filesystem, isn't this fixed? Can anyone still reproduce? I haven't seen this since the embedded server has been implemented.
Comment 7 Petr Jiricka 2012-08-22 11:26:44 UTC 
Closing as FIXED, reopen if still reproducible.
