I detect that this code is problematic. According to the Correctness (CORRECTNESS), EC: Call to equals(null) (EC_NULL_ARG).
This method calls equals(Object), passing a null value as the argument. According to the contract of the equals() method, this call should always return false.

I detect that this code is problematic. According to the Correctness (CORRECTNESS), SA: Self comparison of value with itself (SA_LOCAL_SELF_COMPARISON).
This method compares a local variable with itself, and may indicate a typo or a logic error. Make sure that you are comparing the right things.
