-------------------------------------
Verified status of this issue
2.not sure - I am not sure about this issue, maybe still need to be opened
In issue ODFTOOLKIT-198 Some threads hang if openning a document with multiple
threads
It also said: "If a document is openning with ODFDOM by multiple threads, some
threads hang. By looking into the stack, the problem is caused by HashMap used
in concurrent environment."
> HashMap leads to endless loop in OdfXMLFactory.

> Project: ODF Toolkit
> Issue Type: Bug
> Components: java
> Affects Versions: 0.8.7
> Environment: Operating System: Windows
> Platform: PC
> Reporter: devin
> Assignee: issues
> Fix For: 0.8.7
>
>
> Load two documents concurrently may run into endless loops again and again.
> The reason seems to be a corruption of the HashMap mElementTypes in the Class
> OdfXMLFactory, which causes the call classCache.get(odfName) to infinitely
> loop within line 303 of HashMap.
> We will consider using ConcurrentHashMap to replace HashMap if necessary.
> BTW: setOdfElementClass and setOdfAttributeClass are not used. I think we
> need to improve it.
> Thanks Colin discovered and reported this bug.
