<AWT Dev> RFR: 8259232: Bad JNI lookup during printing

[Phil Race]

Didn't hit this because all the print testing I conducted used the swing print + page dialog but the logging made it easy to find the source of the problem.
I've also done an audit of GET_METHOD_* usages for this pattern - I had previously done it for DECLARE_METHOD* which is the bulk.
