"Null pointer dereference" AND "Nullcheck of value previously dereferenced":

Null pointer dereference

A null pointer is dereferenced here. This will lead to a NullPointerException when the code is executed.

Nullcheck of value previously dereferenced

A value is checked here to see whether it is null, but this value can't be null because it was previously dereferenced and if it were null a null pointer exception would have occurred at the earlier dereference. Essentially, this code and the previous dereference disagree as to whether this value is allowed to be null. Either the check is redundant or the previous dereference is erroneous.
