docs: Returns a boolean to indicate whether there are incomplete RMLTs in the
  current LTC.
  
  @return true if there is an LTC associated with the thread that has resources
  enlisted either for cleanup or for coordination. Under these circumstances,
  it would be illegal for the bean with which the LTC was associated
  to start a global transaction.
