This patch may be sufficient to get the driver to load on Java 9+:

> I'm surprised to be unable to find this issue logged elsewhere, but a quick search yields nothing. Trying to connect with the JDBC driver raises a NoClassDefFoundError for sun.misc.VM, which was removed in Java 9. It is understandable that the full drillbit (or its many dependencies) may have difficult-to-extract dependencies on some sun.misc.* classes, but the JDBC driver should be able to be loaded by any JVM.
>  
> Looking at ./common/src/main/java/org/apache/drill/common/config/DrillConfig.java, it appears that a quick workaround could be to make sun.misc.VM.maxDirectMemory called lazily from the one place that uses it: getMaxDirectMemory()
