RFR 8154962: [TEST] @BeanProperty: add some tests for anonimous classes

[Alexander Stepanov]

Hello,

Could you please review the following fix
http://cr.openjdk.java.net/~avstepan/8154962/webrev.00/index.html
for
https://bugs.openjdk.java.net/browse/JDK-8154962
Just a single test added (AnonymousClassBeanPropertyTest) + minor fixes 
for BeanPropertyTest.java (removed unnecessary "throws" + a couple of 
test cases added).

Thanks,
Alexander
