Description Arthur Ryman CLA 2006-03-13 17:03:41 EST 
I was testing WTP 1.5 M5 and ran into a severe performance problem in JSP content assist. I was getting 10 sec or longer delays for the suggestions to appear, during which time eclipse was "Not Responding". To recreate, do the following:

1. Create a new workspace
2. Create a new Dynamic Web project (use Tomcat 5.0.28, but that shouldn't matter)
3. Create a new JSP
4. Insert in the body <%= new Date
5. Press control+space

There is a long (> 10 sec) delay before the suggestion menu appears.

JDT changed the way javadoc is read which significantly slowed JSP content assist proposal generation.

We might be able to work around it by delaying the "getAdditionalInfo()" call as suggested in the comments for the JDT bug I opened (126277) to track the problem.

Performance of content assist is back to normal in WTP 1.5 RC5. Verfied.

This is part of a mass update to close out all stale WTP defects already verified by the reporter but awaiting closure by the assignee.  If you feel this defect was closed inappropriately, please reopen.

Thanks, John Lanuti
