Subject [jira] [Created] (CASSANDRA-6639) Update Guava to version 16
Date Thu, 30 Jan 2014 04:14:09 GMT
Mikhail Mazursky created CASSANDRA-6639:
-------------------------------------------

             Summary: Update Guava to version 16
                 Key: CASSANDRA-6639
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-6639
             Project: Cassandra
          Issue Type: Improvement
          Components: Core
            Reporter: Mikhail Mazursky
            Priority: Trivial


Currently C* uses Guava 15. I tried to update my code to use Guava 16 and my integration tests,
that use C*, started to produce the following traces:

Exception does not influence the tests and they run ok, however this is disturbing. The cause
is that Guava changed the signature of the mentioned method to return double instead of void
in 16 release. So, can the dependency be updated to avoid the inconvenience? Thanks.

p.s. I found a workaround for integration tests - just add the Guava 15 dependency to the
cassandra-maven-plugin configuration as follows:

{code:xml}
<plugin>
	<groupId>org.codehaus.mojo</groupId>
	<artifactId>cassandra-maven-plugin</artifactId>
	<version>2.0.0-1</version>
	<dependencies>
		<dependency>
			<groupId>com.google.guava</groupId>
			<artifactId>guava</artifactId>
			<version>15.0</version>
		</dependency>
	</dependencies>
<plugin>
{code}
