Description Marco Qualizza CLA 2005-01-13 13:58:34 EST 
Create a new class using the New Class wizard, and, in the wizard, enter the
name of the super class.  There is a *painful* pause for every keypress.  The
problem is that findType is being called 3 times for every key press.  The
second call (NewTypeWizardPage 1300) against java.lang is expensive, and the
third call (NTWP 1305) is *super* expensive (against my project, which has ~6000
types).  I'm sorry, but I can't go any deeper since I really don't know the
Eclipse source code. :-)

Martin, can you please comment.

I realize that 'findType' is not the cheapest method, but so far we never had a
complaint, nor have I experienced what you describe. I have over 14000 types in
my project. I also thought that jdt.core has a type cache for the project.
Is this always like that? Can you check the log for other problems?

Moving to jdt.core to comments.
We do 3 'find types' to find the (unqualified) name in the current package, the
java.lang package, or as fully qualified name.

It was happening on Friday, but now it does happen.  I tried restarting Eclipse
(it had been on all weekend) but that didn't help.  I cannot see anything in the
log file.

Sorry, it was *not* happening on Friday.

Can you reproduce with latest?
If not, we will close as WORKSFORME.

Closing as not reproduced recently. 
Please reopen if you still see a problem and have steps to reproduce.
