Vladimir commented on ODFTOOLKIT-198:
-------------------------------------
I had this issue right now with odfdom-java 0.8.7 from maven:
{code:java}
OdfTextDocument document = OdfTextDocument.loadDocument(new
ByteArrayInputStream(bytes));
{code}
in multiple threads hang with this stacktrace:

> Key: ODFTOOLKIT-198
> URL: https://issues.apache.org/jira/browse/ODFTOOLKIT-198
> Project: ODF Toolkit
> Issue Type: Improvement
> Components: java
> Affects Versions: odfdom-0.8.6
> Environment: Operating System: Windows
> Platform: PC
> Reporter: Ying Chun Guo
> Assignee: issues
> Priority: Minor
>
> 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.
> So we need to change the type of static variables from HashMap to Hashtable.
> One place I found is some variables definition in OdfXMLFactory. There might
> be other places which should be changed.
> Patches will be uploaded later.
> Regards
> Daisy
