(reflect) test/java/lang/reflect/Generics/Probe.java failing

The recent changes to java.util.EnumMap and java.util.IdentityHashMap$Entry (6312706) mean that test/java/lang/reflect/Generics/Probe.java is now failing. The underlying issue is a long standing bug in the signature parser (6476261). Fixing the signature parser this late in jdk7 is likely to be risky so this new bug is submitted to track changing the test to avoid this issue.
