> Though Mahout requires JDK6, mahout-math's pom.xml contains plugin configuration which direct compile for Java5 as following:
> {code}
>      <plugin>
>        <groupId>org.apache.maven.plugins</groupId>
>        <artifactId>maven-compiler-plugin</artifactId>
>        <configuration>
>          <source>1.5</source>
>          <target>1.5</target>
>        </configuration>
>      </plugin>
> {code}
> Furthermore RandomWrapper and DistributionChecks uses String#getBytes(Charset) and Arrays#copyOf() method.
> These methods are not supported in JDK5.
