After upgrading from openjdk 15 to openjdk 16, pentaho data integration (version pdi-ce-9.1.0.0-324) throws a java class error. To reproduce the error message download and install openjdk 16 from https://adoptopenjdk.net/releases.html?variant=openjdk16&jvmVariant=openj9 and start PDI spoon:

bash /opt/pentaho/pdi-ce-9.1.0.0-324/spoo.sh

Error trace:-

It shouldn't have even work with java15, Pentaho is only certified to work with Oracle or OpenJDK java 8: https://help.pentaho.com/Documentation/9.1/Setup/Components_Reference
