[jbosstools-issues] [JBoss JIRA] Commented: (JBIDE-6597) Seam tools are taking big amount of the memory

Snjezana Peco commented on JBIDE-6597:
--------------------------------------

I think that opening page.xml or components.xml isn't the cause of this problem which can be checked by closing and opening components.xml again. Memory usage isn't increased after first opening this file.

In my opinion, the problem is that XModel and KB validator use a lot of memory (opening components.xml probably starts KB Validator).

Adrian,

Could you try the following:
- disable JBoss KB Project Validator using Window<Preferences>Validation
- restart Eclipse and repeat your test case
The memory should be lower than before.


KB Validator aggressively caches pages within the PageContextFactory class. The allocated memory is lower and system performance better if we clear this cache after calling the validator. Attached is a patch.

Re XModel, I haven't found any significant problem. There is a memory leak when closing/deleting a project, but it doesn't have any effect on this case. The solution would be that KBProject.clean() calls libraries.clear() or creates a new method that would clear libraries when the project is closed/deleted.

> Hello! I have a relatively big project:
> - 5000 classes
> ~ 150 seam components
> - 520.xhtml files
> - 20 pages.xml files
> When i open a resource related to seam (like pages.xml, components.xml). The IDE loads the seam plugins, does some computations and takes most of my memory.
> I'm attaching a short video to see what happens and some useful information.
> Eclipse version: 3.5.1 Build id: M20090917-0800
> JBT build: 3.1.0.v200909110340M-H277-M3
