i implemented the solution for the case with .

setLockMode( LockMode.NONE )

checking

lockOptions.getAliasLockCount() == 1 && lockOptions
						.getAliasSpecificLockMode( "this_" ) == LockMode.NONE

Not sure if it's worthwhile to consider the case of

setLockMode(String alias, LockMode lockMode); 

in this case probably is necessary to iterate the lockOptions checking all the aliases have LockMode.NONE.
