Description
With Lambda going in JDK8, use of '_' as an identifier is being deprecated. For JDK8, warnings will be generated for its usage.

A test needs to be written to use '_' as an identifier for all possible usages of identifier and check that warnings are generated for each case.

Test pushed in Lambda repo: http://hg.openjdk.java.net/lambda/lambda/langtools/rev/89bc9300b5e5

See the test provided by JDK-8006561 test/tools/javac/lambda/WarnUnderscoreAsIdent.java Any additional tests should be done by JCK, not here. I recommend this issue should be closed, will not fix.

Go through JLS to get all possible usages of identifier to create a test code.
