// Note for the following code which makes JNI upcalls...
//
// Problem, bug DB 16818166, JBS DB JDK-8015400
// AccessibleContext is a JOBJECT64 which is a jobject (32 bit pointer)
// for a Legacy (XP) build and a jlong (64 bits) for a -32 or -64 build.
// For the -32 build the lower 32 bits needs to be extracted into a jobject.
// Otherwise, if AccessibleContext is used directly what happens is that
// the JNI code consumes the lower 32 of its 64 bits and that is not a
// problem, but then when the JNI code consumes the next 32 bits for the
// reference to the role String it gets the higher 0x00000000 bits from
// the 64 bit JOBJECT64 AccessibleContext variable and thus a null reference
// is passed as the String reference.
//
// Solution:
// Cast the JOBJECT64 to a jobject. For a 64 bit compile this is basically
// a noop, i.e. JOBJECT64 is a 64 bit jlong and a jobject is a 64 bit reference.
// For a 32 bit compile the cast drops the high order 32 bits, i.e. JOBJECT64
// is a 64 bit jlong and jobject is a 32 bit reference. For a Legacy build
// JOBJECT64 is a jobject so this is also basically a noop. The casts are
// done in the methods in JavaAccessBridge::processPackage.
