Modified to allow for unwrapping of PreparedStatements from XAPool prepared statements for CLOB support of greater than 4K in Oracle. This is to allow for OJB to work properly within the context of a Workflow plugin with CLOBs.
A patch has been submitted and incorporated into OJB 1.0.5 to fix this problem in the OJB product. See the following JIRA:
http://issues.apache.org/jira/browse/OJB-101
Also, it appears there was a bug in unwrapping DBCP connections. I patched this to fall back to the database metadata as is done in Spring's NativeJdbcExtractorAdapter.

Modified to fix a problem that Jay was having with the GL batch process. Basically, there was concurrent access by mutliple threads happening against this class and the arrays inside, causing ArrayIndexOutOfBounds exceptions. The multi threading was happening because of a finalize() method being run in a different thread. The solution to this was to synchronize the collections inside and access to the collections.

There was a concurrency issue with a cache of ClassDescriptors held by this class. One instance of an update was not synchronized.
########################################################################### src/java/org/apache/ojb/broker/core/PersistenceBrokerImpl.java ###########################################################################
Fixing OJB bug which throws an NPE when deleting objects with a proxied 1-1 contained object. The original code failed to check the "null-ness" of the object after unwrapping the CGLIB proxy class.
KFSMI-282 : Fixing OJB bug which blanks out the PK fields of the main object when a 1:1 relationship object is null. The original code checked the "null-ness" of the object before unwrapping the CGLIB proxy class.

Added better OJB execption logging.

Changed to fix issue with deletion from "super" table as per the following jira issue in the OJB jira queue:

fixed exception in proxy class when target class has protected setters
src/java/org/apache/ojb/broker/core/proxy/AbstractIndirectionHandler.java ########################################################################### 10-25-2011
Applied fix from Cornell University which allows JavaMelody SQL Monitoring to be used with OJB. (OJB's proxy detection was causing CLOB management to default back to Oracle 8.)

Synchronized access to loadedHMs Collection since concurrent access under load was causing endless loops within the HashMap implenetation when running Java 8. This lead to OOME and StackOverflowErrors, even with fairly minor load.
