Yeah, we didn't update the jre previously because of the android build and libGDX compatibilities. There's actually a really strange bug in the libGDX version we're using that they've patched out (related to a bitshift and comparison in the code that handles collections), so I'd like to update it, as well as the Spine runtime, though they've introduced some breaking changes in the past (right now, we can't rotate the root bone of a Spine skeleton or it causes issues with flipping the skeleton, so we just avoid rotating the root bone).
