             Summary: Add MethodCanBeStatic check via ErrorProne
                 Key: CALCITE-4422
                 URL: https://issues.apache.org/jira/browse/CALCITE-4422
             Project: Calcite
          Issue Type: Improvement
    Affects Versions: 1.26.0
            Reporter: Vladimir Sitnikov


See https://errorprone.info/bugpattern/MethodCanBeStatic

{quote}A private method that does not reference the enclosing instance can be 
static{quote}

Note: the key driver is code readability. If a method is static, it is clear 
that it can't access instance fields, and all it can access is provided via 
arguments.
