Resolution: Won't Fix
no action until JDK21 support
> gremlin groovy tests fail with `Unsupported class file major version 65` with
> JDKs 21 forward

> Key: TINKERPOP-3117
> URL: https://issues.apache.org/jira/browse/TINKERPOP-3117
> Project: TinkerPop
> Issue Type: Bug
> Components: language
> Affects Versions: 3.7.2
> Reporter: Ema Tag
> Priority: Minor
>
> Running tests with java version cause exceptions with error: `Unsupported
> class file major version 65` I did investigate this error myself and I could
> identify the reason in some analyzer of the groovy language, so I could work
> around the problem disabling the analyzer with some groovy compiler settings.
> I've done it both from code:
> {code:java}
> GremlinGroovyScriptEngineFactory factory = new
> GremlinGroovyScriptEngineFactory();
> CachedGremlinScriptEngineManager customizationManager = new
> CachedGremlinScriptEngineManager();
> Map<String, Object> compilerConfigs = new HashMap<>();
> Map<String, Object> optimizationConfigs = new HashMap<>();
> optimizationConfigs.put("asmResolving", false);
> compilerConfigs.put("OptimizationOptions", optimizationConfigs);
> customizationManager.addPlugin(GroovyCompilerGremlinPlugin.build().compilerConfigurationOptions(compilerConfigs).create());
> factory.setCustomizerManager(customizationManager);
> {code}
> and from configuration:
> {code:yaml}
> scriptEngines: {
> gremlin-groovy: {
> plugins: {
> # ... other configs
> org.apache.tinkerpop.gremlin.groovy.jsr223.GroovyCompilerGremlinPlugin:
> {compilerConfigurationOptions: { OptimizationOptions: { asmResolving: false}}}
> }
> }
> }
> {code}
> this could be done directly in a generic way for all the implementations
> adding the setting here:
> https://github.com/apache/tinkerpop/blob/master/gremlin-groovy/src/main/java/org/apache/tinkerpop/gremlin/groovy/jsr223/GremlinGroovyScriptEngine.java#L756
