I am getting the following error:

BUG! exception in phase 'semantic analysis' in source unit 'calculator_valuation_1783629867000_22037' Unsupported class file major version 65

The report runs in my Jaspersoft studio where I design it, but not in ART. NOTE: this did run ok last month, but not this month.

Both machines (mine and the server) run Linux mint and report the java version as:

java -version
openjdk version "21.0.11" 2026-04-21
OpenJDK Runtime Environment (build 21.0.11+10-1-24.04.2-Ubuntu)
OpenJDK 64-Bit Server VM (build 21.0.11+10-1-24.04.2-Ubuntu, mixed mode, sharing)

How do I fix this?

Thanks.
