Nasty warnings on make #18

Open bholtdwyer opened 1 year ago

Hi! When I tried to make the jar, it gave me some warnings about "illegal" operations that "will be denied in a future release". Just FYI.

git clone https://github.com/tberg12/ocular.git
cd ocular
./make_jar.sh

I then get a fatal error:

Use an older version of javasdk (say java 8) will resolve it.
