Notes

Known Issues

These are to be converted to Github Issues

1. Maven plugin broken due to ASM Java 9 bugs:

   • maven-dependency-plugin -- See MDEP-559
   • modernizer -- gaul/modernizer-maven-plugin#60

   Workaround is to disable the plugins via properties:

   <op.check.skip-dependency>true</op.check.skip-dependency>
   <op.check.skip-modernizer>true</op.check.skip-modernizer>
