/**
 * Property editor that can convert String into TransactionAttributeSource.
 * The transaction attribute string must be parseable by the
 * TransactionAttributeEditor in this package.
 *
 * <p>Strings are in property syntax, with the form:<br>
 * <code>FQCN.methodName=&lt;transaction attribute string&gt;</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".
