[jbosstools-issues] [JBoss JIRA] Commented: (JBDS-259) JBDS1.0 Massive Memory Leak using JBoss Tool HTML Editor on .XHTML files
[ http://jira.jboss.com/jira/browse/JBDS-259?page=comments#action_12401691 ]
Snjezana Peco commented on JBDS-259:
------------------------------------
I can reproduce this case (including note 2) in JBoss Tools 2.0.0
The issue doesn't exist in the latest CVS. it has been fixed within JBIDE-1105.
However, there is a memory leak when entering some jsf html tag (<h:form>, for
instance). The memory is released when clicking Refresh or closing the editor.
This leak is caused by the VpePageContext.addBundleDependency(Element sourceNode) method.
The Element class doesn't implement equals/hashCode and the bundleDependencySet set
will be continuously increasing until the user clicks Refresh or closes the editor
(calling the VpeVisualDomBuilder.rebuildDom() method).
Attached is a patch for this issue.
I have also noticed that there is a leak when dragging an element from the palette to the
source editor.
I haven't found a test case for this issue yet, but will try to find and fix it.

Original Post:
There seems to be a major memory leak making the JBoss HTML Editor completely unusable.
Mem usage in Task Manager shows as follows:
* 111,448 On a fresh open of Jboss Dev Studio
* 189,144 Opening an .xhtml file (in visual/source mode) using in the "Jboss HTML
Editor"
* 197,932 Removed a blank line from the source & saved
* 207,180 Inserted a blank line in source & saved
* 211,168 Inserted a space in source & saved
* 357,392 Inserted & Deleted a blank line in source: repeat 20x (no saves in
between)
Clearly there is some dramatic memory problem here.
Note:
1) The problem does not seem to occur when mode is set to "Source"
2) The memory is not released even if the HTML Editor is closed
