> When running on Java 11 and deploying bundles providing SPI Script Engine Factories platform provided script engine factories might be registered more than once. This is evidenced by the failure of the {{org.apache.sling.scripting.core.impl.jsr223.SlingScriptEngineManagerTest#testBundledScriptEngineFactory}} test.
> This happens because the bundle class loader used for the service loader through which SPI Script Engine Factories are loaded also provides the platform provided factories. The solution would be to make sure that the generated {{SortableScriptinEngineFactories}} are added to the internal set only if they rely on different delegate factories.
