Description

I am getting the following error on Java 16:

Caused by: java.lang.NoClassDefFoundError: Could not initialize class org.apache.ignite.IgniteJdbcThinDriver
	at java.base/java.lang.Class.forName0(Native Method)
	at java.base/java.lang.Class.forName(Class.java:466)
	at java.sql/java.sql.DriverManager.isDriverAllowed(DriverManager.java:555)
	at java.sql/java.sql.DriverManager.isDriverAllowed(DriverManager.java:547)
	at java.sql/java.sql.DriverManager.getDrivers(DriverManager.java:449)
	at java.sql/java.sql.DriverManager.getDrivers(DriverManager.java:426)
	at com.zaxxer.hikari.util.DriverDataSource.<init>(DriverDataSource.java:60)

I am not even trying to use the JDBC driver. Unfortunately, Hikari performs Class.forName() on all JDBC drivers in the classpath, and I have a dependency on ignite-core.jar. The jar is part of the Java thick client.

Currently, this issue prevents me from upgrading to Java 16
