I don't think build.xml changes are related, right?

> In jenkins, [it |https://builds.apache.org/job/Pig-trunk/1935/#showFailuresLink] shows that TestLogicalPlanBuilder#testQuery90 fails. After debugging, it always fails in 
> [Line1139 |https://github.com/apache/pig/blob/trunk/test/org/apache/pig/test/TestLogicalPlanBuilder.java#L1138]
> {code}
>  Assert.assertTrue(foreach.getSchema().toString( false ).equals("mygroup:tuple(myname:chararray,myage:int),mycount:long"));
> {code}
> The script is 
> {code}
> a = load 'myfile' as (name:Chararray, age:Int, gpa:Float);b = group a by (name, age);c = foreach b generate group as mygroup:(myname, myage), COUNT(a) as mycount;store c into 'output';
> {code}
>         
> The reason why fails is because the schema of mygroup(myname,myage) is 
> mygroup(myname:bytearray,myage:bytearray) and this user-defined schema is assigned to c. so the schema of c is
> not mygroup:tuple(myname:chararray,myage:int) but mygroup:tuple(myname:bytearray,myage:bytearray).
> This problem is imported since PIG-2315 as ForEachUserSchemaVisitor is used in [LogicalPlan|https://github.com/apache/pig/blob/trunk/src/org/apache/pig/newplan/logical/relational/LogicalPlan.java#L179].
