Version: v0.8.1 Java version used to run: Java 15

The target JAR uses Java 8 as far as I know, but it has some libraries that should be backwards compatible or such for my understanding, otherwise who would on the earth still uses Java 5? There is Java 15!

Hi, thanks for the report, I'll take a look at it when I have some free time. (May be during this or the next week.)

TheDGOfficial commented 3 years ago

Any updates on this?

Sipkab commented 3 years ago

Sorry, I didn't have much time for this, don't have an ETA yet.

@Sipkab Did you ever get around to this? No pressure, just curious.
