----------------------------------------
Hi Ludger,
Is this issue fixed in 2.10? Is it the same issue as mentioned in the following 2.10 release notes? Thanks in advance.
Fixed a bug in the DOM implementation where a static text Node field in AttrImpl broke thread-safety of mutations in independent documents from within an event listener. This was also a potential memory leak. [Ludger Bünger]
> Memory leak: Elements with id attributes are not garbage collectable if the id attribute is not removed.

https://issues.apache.org/jira/browse/XERCESJ-1430> Project: Xerces2-J
> Issue Type: Bug
> Components: DOM (Level 3 Core)
> Affects Versions: 2.9.1
> Reporter: Ludger Bünger
> Attachments: IdentifiersWeakValuePatch.txt

>
> Memoryleak:
> Inside CoreDocumentImpl a HashTable resides that holds an id string to element mapping.
> If an element is removed from the DOM this Map is only updated if one also removes the id attribute.
> Thus the element is not garbage collectable.
> Solution:
> Use an Map implementation that holds only a weak reference to it's values.
> See attached patch
