Expected: major version is 52
Actual: major version is 53

Steps to reproduce the problem:

Versions:

• jOOλ: org.jooq:jool-java-8:0.9.13+
• Java: Oracle JDK 8

Stacktrace

Failed to define class org.jooq.lambda.fi.util.function.CheckedFunction in Module "deployment.identity.war" from Service Module Loader: java.lang.UnsupportedClassVersionError: Failed to link org/jooq/lambda/fi/util/function/CheckedFunction (Module "deployment.identity.war" from Service Module Loader): org/jooq/lambda/fi/util/function/CheckedFunction has been compiled by a more recent version of the Java Runtime (class file version 53.0), this version of the Java Runtime only recognizes class file versions up to 52.0

I'm assuming this resolved itself? I cannot confirm that jool-java-8 has the wrong version number.

[vbaidak]

Yes, @lukaseder . I had both jool dependencies in classpath, so it was my mistake. Sorry for taking your time

When
major version 53 is newer than 52, the highest major version supported by this compiler.
use

implementation("org.jooq:jool-java-8:0.9.14")

instead

implementation("org.jooq:jool:0.9.14")
