>             Project: Tools (JBoss Tools)
>          Issue Type: Bug
>          Components: hibernate
>    Affects Versions: 3.3.0.Beta1
>            Reporter: Viacheslav Kabanovich
>            Assignee: Dmitry Geraskov
>             Fix For: 3.3.0.Beta3

>
> EXECUTE: Open HQL Editor, and type some long query using tabs (\t) instead of usual whitespaces.
> EXECUTE: Send the query into Hibernate Query Result view.
> ASSERT: New tab folder is added to the view in 1-2 seconds even for queries as long as 1000 characters.
> ASSERT: Resize of the view goes without delays.
> FAILURE: For a query of 120 characters, including 15 \t characters, creation of new tab folder, and each subsequent resize of the view takes 7 seconds. Doubling text size increases time 8 times.
> SWT methods CTabFolderRenderer.shortenText(GC, String, int, String), TextLayout.getPreviousOffset(int,int), GC.textExtent(String,int) have poor performance for long strings with \t characters. I have created issue https://bugs.eclipse.org/bugs/show_bug.cgi?id=374987
> Class HQLQueryPage sets tab name as 
> {code}
> setTabName(getQueryString().replace('\n', ' ').replace('\r', ' '));
> {code}
> This issue may be solved by modifying it as
> {code}
> setTabName(getQueryString().replace('\n', ' ').replace('\r', ' ').replace('\t', ' '));
> {code}
