#766 support Java 13

[Jason S]

Can you support JDK13?

Getting error

Error: Can't read [C:\Usersxxx\devxxxx\targetxxxx1-0-SNAPSHOT.jar(;;;;;;;!META-INF/maven/**)] (Can't process class [com/logpath/client/cache/CacheForFileKey.class] (Unsupported version number [57.65535] (maximum 57.0, Java 13)))

hmmm, I'm using preview features, which gives a different class format.

ProGuard supports Java 13, but you should update your compiler from the
beta release of Java 13 to the official release.

ProGuard doesn't support any features that are in the preview format, but not in the final format. At this time, ProGuard works fine with for example

java version "13" 2019-09-17
Java(TM) SE Runtime Environment (build 13+33)
Java HotSpot(TM) 64-Bit Server VM (build 13+33, mixed mode, sharing)

We'll support any features that make in into Java 14...
