[jira] Updated: (HADOOP-1294) Fix unchecked warnings in main Hadoop code under Java 6.

["Tom White (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HADOOP-1294?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Tom White updated HADOOP-1294:
------------------------------

    Attachment: java6_unchecked.patch

This is occurring because the getConstructor method on Class changed between Java 5 and 6, from:

public Constructor<T> getConstructor(Class... parameterTypes)

to

public Constructor<T> getConstructor(Class<?>... parameterTypes)

This patch should fix the warning. I haven't managed to test it on Java 6 - Tahir, would you be able to try it please?
