[8] Review request for 8027648: Type of overridden property is resolved incorrectly

[sergey malenkov]

Hello,

Could you please review the following fix:
fix: http://cr.openjdk.java.net/~malenkov/8027648.8.0/
bug: https://bugs.openjdk.java.net/browse/JDK-8027648

Sometimes the Introspector does not support Generics.
We should allow to use assignable property types there.

Thanks,
SAM
