final void atomicUnlockImpl (boolean notifyUnmodifyIfNoMods) {
boolean noModsAndOuterUnlock = false;
synchronized (this) {
if (atomicDepth <= 0) {
throw new IllegalStateException("atomicUnlock() without atomicLock()"); // NOI18N
}

// inside the atomic section.
// Fire VetoableChangeListener outside Document lock
