The tests are not supposed to call setup() multiple times for the same
operator instance. According to the Java doc of the `Component.setup()`
callback to setup() "is made exactly once during the operator lifetime." If a
test relies on setup() to clean or reinitialize an operator state, such test
should be modified.
It will be good to fix all operators that are frequently used. Please file
new JIRA for such operators.
