Nicolas Liochon commented on PHOENIX-2620:
------------------------------------------
The branch is took at is master yes?
Then if I look at this branch in github:
- the bug is still there
- the patch I uploaded 3 days ago still applies
- a similar issue was fixed a few months ago for JavaPattern#replaceAll
(PHOENIX-1870) but it did not fix the JavaPattern#matches method...
> NPE in org.apache.phoenix.expression.util.regex.JavaPattern.matches
