Any workaround code for able issue. I am using latest version of 
xmlbeans3.0.1 and POI 4.0.1.

+1 for more information, like container type and version, platform, jre,
etc.  I've been using poi in a tomcat deployed webapp for nearly 15 years
and never seen this.

There are many places in XmlBeans where ThreadLocal is used and as far as I
could see after a quick glance, there is no easy workaround, so it would be
good if you can report a bug at
https://issues.apache.org/jira/secure/CreateIssue!default.jspa with some
more description about what type of processing you perform.

Thanks... Dominik.
