Call to equals() comparing different types

I have found the bug with the FindBugs tool,
the description is:

Call to equals() comparing different types
This method calls equals(Object) on two references of
different class types with no common subclasses.
Therefore, the objects being compared are unlikely
to be members of the same class at runtime
(unless some application classes were not analyzed,
or dynamic class loading can occur at runtime).
According to the contract of equals(), objects of
different classes should always compare as unequal;
therefore, according to the contract defined by
java.lang.Object.equals(Object), the result of this
comparison will always be false at runtime.

Bug kind and pattern: EC - EC_UNRELATED_TYPES
