Aleksey Yeschenko commented on CASSANDRA-8730:
----------------------------------------------
bq. any chance to see this patched in 2.0 branch?
2.0 line has officially been declared EOL, and the next release (2.0.17) is
going to be the final one.
You could apply the patch manually though and build from source.
