Description

Methods from java.lang.Objects are implicitly present in all classes and interfaces.
The Report Checker doesn't report calls on such methods in interfaces.
A test case illustrating this issue can be found at
framework/tests/report/Interface.java
(pending merge of upcoming PR).

This issue should be investigated also for other checkers, to ensure that e.g. method overriding and pre-condition checks on methods are implemented correctly.

Research direction

Start with the test case in framework/tests/report/Interface.java and the Report Checker entry point. Reproduce the missing reports for methods from java.lang.Object, then inspect how other checkers handle method overriding and pre-condition checks. Done means the test passes and the affected checker behavior is covered.
