Sonar: Method params shouldn't be reassigned

Fix 14 instances of Sonar issue "Method parameters, caught exceptions
and foreach variables should not be reassigned" labeled as Major. The
rule description says: "While it is technically correct to assign to
parameters from within method bodies, it is better to use temporary
variables to store intermediate results. This rule will typically detect
cases where a constructor parameter is assigned to itself instead of a
field of the same name, i.e. when this was forgotten. Allowing
parameters to be assigned to also reduces the code readability as
developers will not be able to know whether the original parameter or
some temporary variable is being accessed without going through the
whole method. Moreover, some developers might also expect assignments of
method parameters to be visible from callers, which is not the case and
can confuse them. All parameters should be treated as final."
