Robert Muir commented on LUCENE-3538:
-------------------------------------
Hi Furkan, thanks for looking into this. I get a couple warnings when running
the following commands with a java7 compiler:
I'm using "1.7.0_17"
{noformat}
svn co https://svn.apache.org/repos/asf/lucene/dev/trunk
cd trunk/lucene
ant compile > ../compile.log
{noformat}
lucene/analysis/common module:
{noformat}
[javac] Compiling 360 source files to
/home/rmuir/workspace/lucene-trunk/lucene/build/analysis/common/classes/java
[javac]
/home/rmuir/workspace/lucene-trunk/lucene/analysis/common/src/java/org/tartarus/snowball/Among.java:46:
warning: [rawtypes] found raw type: Class
[javac] private static final Class<?>[] EMPTY_PARAMS = new Class[0];
[javac] ^
[javac] missing type arguments for generic class Class<T>
[javac] where T is a type-variable:
[javac] T extends Object declared in class Class
...
{noformat}
lucene/queries:
lots of warnings unfortunately
{noformat}
[javac] missing type arguments for generic class Map<K,V>
[javac] where K,V are type-variables:

[javac] V extends Object declared in interface Map

warning: [rawtypes] found raw type: Map
[javac] public FunctionValues getValues(Map fcontext, AtomicReaderContext
readerContext) throws IOException {
{noformat}
lucene/queryparser:
again lots of warnings, some are in generated code which is more difficult, but
also some silly ones, like:
{noformat}
[javac]
/home/rmuir/workspace/lucene-trunk/lucene/queryparser/src/java/org/apache/lucene/queryparser/flexible/standard/processors/GroupQueryNodeProcessor.java:54:
warning: [dep-ann] deprecated item is not annotated with @Deprecated
[javac] public class GroupQueryNodeProcessor implements QueryNodeProcessor {
{noformat}
lucene/memory, lucene/highlighter, lucene/benchmark, and lucene/spatial also
have warnings too.
