> Reporter: Laszlo Gaal
> Assignee: Zoltán Borók-Nagy
> Priority: Critical
>
> In builds executed fully in a JDK17-based environment the Iceberg REST
> catalog fails to come up in the minicluster, throwing the below exceptions:
> {code}
> Picked up JAVA_TOOL_OPTIONS:
> Error: A JNI error has occurred, please check your installation and try again
> Exception in thread "main" java.lang.UnsupportedClassVersionError:
> org/apache/iceberg/rest/IcebergRestCatalogTest has been compiled by a more
> recent version of the Java Runtime (class file version 61.0), this version of
> the Java Runtime only recognizes class file versions up to 52.0

> This looks like the REST catalog wanting to start up using a Java 8 JRE (for
> unknown reasons) while using Java17 jars.
> This of course fails all the REST catalog tests during CUSTOM_CLUSTER tests.
