Hi!

I have problems opening JSP and XHTML files. When choosing a JSP file from the "Open ressource" dialog, I have to wait more than a minute (far more than a minute!) until the file is finally shown in the editor. The Eclipse process is really busy during that period of time and the program does not respond.

If I remember correctly the problem occurred when upgrading Eclipse from 3.5.1 to 3.6 and remains ever since. I also upgraded to Eclipse 3.6.1 with no effect. I tried out the latest Indigo build yesterday and had no problems opening JSP files. Unfortunately Indigo is not stable enough to be used in production environment right now so upgrading is not an option at the moment.

The issue seems to be unrelated to the file size.

I checked some combinations of JSP files and found out that opening the file is extremely slow as soon as I use a taglib. Opening a file containing the following line takes about one minute:

<%@ taglib prefix="bean" uri="http://struts.apache.org/tags-bean"%>

If I remove the line everything seems to be fine.

The issue is reproducable for Eclipse 3.6.1 on other machines/installations with Windows 7 / 64 bit as well.

Here is a thread dump that was created while Eclipse is trying to open the JSP file:
