Hi,

there currently exists a very very annoying bug, where simply opening two XML editors results in delays of almost minutes when opening any dialog, e.g. the find dialog (Ctrl+F).

I opened https://bugs.eclipse.org/bugs/show_bug.cgi?id=391127 against Platform / SWT, because there is no WTP plugin showing up in any stack traces when taking thread dumps. Also, I guess that the XML editor in Juno doesn't behave differently from the one for the 3.x stream, so this seems to be a platform bug.

As you may have heard, there isn't many developers anymore assigned to Eclipse platform. There wasn't any feedback from the team in the bug report since they were able to reproduce it. My guess is that this is due to their lack of resources.

It would be great if any WTP developer involved with the XML editor could have a look, it's easy to reproduce:

download eclipse-SDK-4.2.1-linux-gtk-x86_64.tar.gz
install "Eclipse XML Editors and Tools 3.4.1.v201208170345-7H7GFeFDxumUpsw5rgjWnKDrsz0p4ymwjQz00T2S" from Juno update site
create two empty XML files and haven them open in editors
open *any* dialog, e.g. find dialog (won't open in empty editor), or "About Eclipse SDK"
observe delay

Since the XML editor is pretty much ubiquitous and hard to avoid working with, I'd think this is a severe bug for e4 on Linux. So if you have an idea what the XML editor might be doing, or what's going wrong in platform, it would be great if you could help out and comment on the bug!

Best regards,
Jörg
