JDK 9+: ClassCastException when loading H2 Driver #7

Closed TheFlagCourier closed 3 years ago

TheFlagCourier commented 5 years ago

iConomy5 is unusable on anything over JDK1.8. Most Linux distributions use JDK 11 as their default java implementation, unless the end user explicitly overrides that or the hosting provider does. Example: default-jre defaults to OpenJDK 11 on Debian Stable and Ubuntu LTS.
