Subject [jira] [Created] (LUCENE-3850) Fix rawtypes warnings for Java 7 compiler

Fix rawtypes warnings for Java 7 compiler
-----------------------------------------

                 Key: LUCENE-3850
                 URL: https://issues.apache.org/jira/browse/LUCENE-3850
             Project: Lucene - Java
          Issue Type: Improvement
    Affects Versions: 3.5, 4.0
            Reporter: Uwe Schindler
            Assignee: Uwe Schindler
             Fix For: 3.6, 4.0


Java 7 changed the warnings a little bit:
- Java 6 only knew "unchecked" warning type, applying for all types of generics violations,
like missing generics (raw types)
- Java 7 still knows "unchecked" but only emits warning if the call is really unchecked. Declaration
of variables/fields or constructing instances without type param now emits "rawtypes" warning.

The changes above causes the Java 7 compile now emit lots of "rawtypes" warnings, where Java
6 is silent. The easy fix is to suppres both warning types: @SuppressWarnings({"unchecked","rawtypes"})
for all those places. Changes are easy to do, will provide patch later!
