thanks and I will take a look. We already modified xml beans jar and removed
all soft references and it resolved our issue for now.

Certainly, take a look at
XmlBeans.typeLoaderForClassLoader()
XmlBeans.typeLoaderForResource() and
XmlBeans.typeLoaderUnion()

is it possible for me to have a separate resource loader for .xsb? it
looks like JNLP class loader is not thread safe. It is trying to call "put" on
HashMap but hash map is not thread safe. It may cause the CPU to spin. Please
advice and it is really appreciated. We are really happy with xml bean
performance but this issue is causing lot of noise on our side.
Thanks for your time.

In this case: two threads are parsing two different byte arrays to
generate java objects. yes, xml bean is looking for a .xsb resource but it is
spinning. I don't set unsync option, so what is the default behavior?
we use xml beans 2.3.
we don't validate the using xml bean. What we have is server is
generating xml using xml beans and send it over http. The client is reading it
off the output stream and generate bytes array and try to parse using xml beans.

Subject: Re: Help with XML Beans
So your application is "generating xml messages or parsing byte arrays
to generate java objects"? Can you determine which one? From the stack
trace you posted is looked like XMLBeans is trying to resolve
something from the SchemaTypeSystem and the hang is caused by the way
JNLP is getting the resource. Can you confirm? Which resource is it
trying to get?
What is the option you have set for
http://xmlbeans.apache.org/docs/2.0.0/reference/org/apache/xmlbeans/XmlOptions.html#setUnsynchronized()
Which version are you using?
Is it possibly related to:
http://issues.apache.org/jira/browse/XMLBEANS-46
http://issues.apache.org/jira/browse/XMLBEANS-328
http://issues.apache.org/jira/browse/XMLBEANS-345
(it didn't look related, but I thought I'd mention anyways)
