Handling large XML document

When I am trying to store a large XML document of 4.4MB by using the
"Client" example, the following messages appear in the console starting
ozone:

[error](315) Transaction: blockedBy()
    java.lang.NullPointerException
        at java.util.Hashtable.get(Hashtable.java:320)

Although the storing process can be finally finished after an hour, the
query process is very slow when I tried to query the large document.
Also, querying other documents are slow too even for very small document
after storing the large documents.

Thanks for your kind attention.
