860 // AccessibleContext is a JOBJECT64 which is a jobject (32 bit pointer)
861 // for a Legacy (XP) build and a jlong (64 bits) for a -32 or -64 build.
862 // For the -32 build the lower 32 bits needs to be extracted into a jobject.
863 // Otherwise, if AccessibleContext is used directly what happens is that
864 // the JNI code consumes the lower 32 of its 64 bits and that is not a
865 // problem, but then when the JNI code consumes the next 32 bits for the
866 // reference to the role String it gets the higher 0x00000000 bits from
867 // the 64 bit JOBJECT64 AccessibleContext variable and thus a null reference
868 // is passed as the String reference.
869 //
870 // Solution:
871 // Cast the JOBJECT64 to a jobject. For a 64 bit compile this is basically
872 // a noop, i.e. JOBJECT64 is a 64 bit jlong and a jobject is a 64 bit reference.
873 // For a 32 bit compile the cast drops the high order 32 bits, i.e. JOBJECT64
874 // is a 64 bit jlong and jobject is a 32 bit reference. For a Legacy build
875 // JOBJECT64 is a jobject so this is also basically a noop. The casts are
876 // done in the methods in JavaAccessBridge::processPackage.
