RFR: 8304717: Declaration aliasing between boolean and jboolean is wrong [v2]

[Julian Waters]

> A couple of spots wrongly refer to boolean and jboolean as the same thing. While this does still compile thanks to a happy accident and implicit conversions, they are not the same at all, and should be fixed before a future compiler error happens if their declarations are touched
