[7u80] Request for approval: 8015780: java/lang/reflect/Method/GenericStringTest.java failing

[Seán Coffey]

This testcase fix should have been ported to jdk7u-dev after JDK-6695379 
was fixed. The JDK 8 test changes apply cleanly. The ProblemList.txt 
file does not need to be edited since 
java/lang/reflect/Method/GenericStringTest.java test is not excluded in 
7u-dev

jdk8 changeset : http://hg.openjdk.java.net/jdk8/jdk8/jdk/rev/70c8f4a4b8d6
bug ID : https://bugs.openjdk.java.net/browse/JDK-8015780
