    GROOVY-7611: java.util.Optional should evaluate to false if empty (Java8 VMPlugin)

    Target for this would be `2_5_X` and above.  For `2_5_X` and `2_6_X` it would require that the release process build with JDK 8 so would need to backport some of the build checks for Java version to those branches.

> In the spirit of the rest of the Groovy truth semantics, I suggest that an empty {{java.util.Optional}}, which is essentially a stream-safe equivalent of {{null}}, should evaluate to false: {{asBoolean()}} should simply delegate to {{isPresent()}}.
