org.bukkit.Location#add / org.bukkit.Location#subtract not having an affect on values.

[PlayfulSeal]

Expected behavior

Location location = ...
Location above = location.add(0, 1, 0);
Location below = location.subtract(0, 1, 0);
is the code that I have. For some reason, location, above and below all return the same values.

Observed/Actual behavior

Results of a Logger.info
Location=Location{world=CraftWorld{name=world},x=-3.0,y=-59.0,z=0.0,pitch=0.0,yaw=0.0}
above=Location{world=CraftWorld{name=world},x=-3.0,y=-59.0,z=0.0,pitch=0.0,yaw=0.0}
below=Location{world=CraftWorld{name=world},x=-3.0,y=-59.0,z=0.0,pitch=0.0,yaw=0.0}

Steps/models to reproduce

Location location = ...
Location above = location.add(0, 1, 0);
Location below = location.subtract(0, 1, 0);

check the javadocs, add modifies and returns the same location, the result you are seeing is expected.
try logging location before and after add and you will see the change.

Locations are mutable as mini said, if you clone the location before adding/subtracting it'll work.
