wtf: impl of impl

(Hibernate code)

package org.hibernate.impl;
...
public final class SessionImpl extends AbstractSessionImpl {
...
  SessionImpl(
    final Connection connection,
    final SessionFactoryImpl factory,
    final boolean autoclose,
    final long timestamp,
    final Interceptor interceptor,
    final EntityMode entityMode,
    final boolean flushBeforeCompletionEnabled,
    final boolean autoCloseSessionEnabled,
    final ConnectionReleaseMode connectionReleaseMode) {
  super( factory );
...

Hibernate pearls

		// let the interceptor inspect the instance to decide
		Boolean isUnsaved = session.getInterceptor().isTransient(entity);
		if (isUnsaved!=null) return isUnsaved.booleanValue();
