/**
* Property editor that converts a String into a {@link TransactionAttributeSource}.
* The transaction attribute string must be parseable by the
* {@link TransactionAttributeEditor} in this package.
*
* <p>Strings are in property syntax, with the form:<br>
* <code>FQCN.methodName=<transaction attribute string></code>
*
* <p>For example:<br>
* <code>com.mycompany.mycode.MyClass.myMethod=PROPAGATION_MANDATORY,ISOLATION_DEFAULT</code>
*
* <p><b>NOTE:</b> The specified class must be the one where the methods are
* defined; in case of implementing an interface, the interface class name.
*
* <p>Note: Will register all overloaded methods for a given name.
* Does not support explicit registration of certain overloaded methods.
* Supports "xxx*" mappings, e.g. "notify*" for "notify" and "notifyAll".
