org.apache.commons.dbcp.DelegatingStatement
A base delegating implementation of Statement.
All of the methods from the Statement interface
simply check to see that the Statement is active,
and call the corresponding method on the "delegate"
provided in my constructor.
Extends AbandonedTrace to implement Statement tracking and logging of code which created the Statement. Tracking the Statement ensures that the Connection which created it can close any open Statement's on Connection close.

Statement is not a
DelegatingStatement, returns it,
otherwise recursively invokes this method on
my delegate.
Hence this method will return the first delegate that is not a DelegatingStatement or null when no non-DelegatingStatement delegate can be found by transversing this chain.
This method is useful when you may have nested
DelegatingStatements, and you want to make
sure to obtain a "genuine" Statement.
