Ben Hood commented on CASSANDRA-7454:
-------------------------------------

I can confirm that this fix (as applied to 2.1-rc4) has resolved part of the an issue reported in https://issues.apache.org/jira/browse/CASSANDRA-7566.

When I run the the TestReprepareStatement test case from the gocql integration suite against the 2.1-rc3 tarball, it fails:

{code}
bool:gocql 0x6e6562$ go test . -v -test.run=TestReprepareStatement
=== RUN TestReprepareStatement
--- FAIL: TestReprepareStatement (0.31 seconds)
	cassandra_test.go:588: Failed to execute query for reprepare statement: java.lang.NullPointerException
FAIL
exit status 1
{code}

But when I run it against the 2.1-rc4 tarball, it passes:

{code}
bool:gocql 0x6e6562$ go test . -v -test.run=TestReprepareStatement
=== RUN TestReprepareStatement
--- PASS: TestReprepareStatement (0.25 seconds)
PASS
ok  	github.com/relops/gocql	0.267s
{code}
