Mikhail Antonov commented on HBASE-13273:
-----------------------------------------
2 options I can see is to make EMPTY_RESULT object private and provide method
getEmptyResult(), returning new cloned empty Result, or make Result object
immutable (which means copyFrom() method should be removed)? Doesn't look like
backward-compatible either?
> Make Result.EMPTY_RESULT read-only; currently it can be modified
> ----------------------------------------------------------------

> Key: HBASE-13273
> URL: https://issues.apache.org/jira/browse/HBASE-13273
> Project: HBase
> Issue Type: Bug
> Affects Versions: 0.98.0, 1.0.0
> Reporter: stack
> Labels: beginner
> Fix For: 2.0.0, 1.0.1, 1.1.0, 0.98.12

> Again from [~larsgeorge]
> Result result2 = Result.EMPTY_RESULT;
> System.out.println(result2);
> result2.copyFrom(result1);
> System.out.println(result2);
> "What do you think happens when result1 has cells? Yep, you just modified the
> shared public EMPTY_RESULT to be not empty anymore."
> Fix. Result should be non-modifiable post-construction.
