Dennis Balkir created OFBIZ-9565:

             Summary: [FB] Package org.apache.ofbiz.base.lang.test
                 Key: OFBIZ-9565
                 URL: https://issues.apache.org/jira/browse/OFBIZ-9565
             Project: OFBiz
          Issue Type: Sub-task
          Components: base
    Affects Versions: Trunk
            Reporter: Dennis Balkir
            Priority: Minor

- ComparableRangeTests.java:82, RV_RETURN_VALUE_IGNORED_NO_SIDE_EFFECT
Return value of method without side effect is ignored

This code calls a method and ignores the return value. However our analysis shows that the
method (including its implementations in subclasses if any) does not produce any effect other
than return value. Thus this call can be removed.

We are trying to reduce the false positives as much as possible, but in some cases this warning
might be wrong. Common false-positive cases include:

- The method is designed to be overridden and produce a side effect in other projects which
are out of the scope of the analysis.

- The method is called to trigger the class loading which may have a side effect.

- The method is called just to get some exception.

If you feel that our assumption is incorrect, you can use a @CheckReturnValue annotation to
instruct FindBugs that ignoring the return value of this method is acceptable.
