> We insert rows into a table using the following prepared statement (through JDBC):
> INSERT INTO USER1.PSTORE values(?,?, XMLPARSE(document CAST (? AS CLOB) preserve whitespace))
> where each of the ?'s are replaced with a string.
> One thread runs fine. Two or more result in the following exception: 
> org.apache.derby.client.am.SqlException: Java exception: 'FWK005 parse may not be called while parsing.: org.xml.sax.SAXException'.
> 	at org.apache.derby.client.am.SqlException.<init>(Unknown Source)
> 	at org.apache.derby.client.am.SqlException.<init>(Unknown Source)
> We believe that this comes from the dBuilder.parse(InputSource) method.
