> The ES_COMPARING_STRINGS_WITH_EQ detector worked because in Java the ==
> operator compares objects for reference equality, but not string literals
> contained in these objects.
> According to
> [one](https://github.com/apache/directory-server/commit/cfa2152efaa693368634e5d278890f7f5d2c9914#diff-90992891001769bbc1422416e6c9fe2e0ff73afbc5660f877244f2545b95f58fL353)
> of the previous commits, here we have the following logic: we excpected to
> get the comparison of string literals contained in these objects.

> Using the _equals(Object)_ method here seems to be a better practice.
