When moving the Sling CI jobs to a new Java version ( 8 → 11, 11 → 17 ) there are certain failures that reoccur. This page documents them so that they are easier to remediate on follow-ups.

Pax-Exam test failures
When I upgrade to the latest Mockito-inline (5.2.0) from 3.5.11 then the instrumentation does work but the Pax IT test all time out because it is unable to lookup Sling services:
[INFO] Running org.apache.sling.graphql.core.it.GraphQLScriptEngineIT [ERROR] Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 21.341 s <<< FAILURE! - in org.apache.sling.graphql.core.it.GraphQLScriptEngineIT [ERROR] org.apache.sling.graphql.core.it.GraphQLScriptEngineIT.testEnginePresent Time elapsed: 10.114 s <<< ERROR! org.ops4j.pax.swissbox.tracker.ServiceLookupException: gave up waiting for service javax.script.ScriptEngineFactory at org.ops4j.pax.swissbox.tracker.ServiceLookup.getService(ServiceLookup.java:199)
Outdated Felix Framework bundle
When inspecting the output of Pax-Exam tests the following error can be found java.lang.reflect.InaccessibleObjectException: Unable to make field private static final java.lang.Object java.net.URL.streamHandlerLock accessible: module java.base does not "opens java.net" to unnamed module @6205ec9d

Remediation: update to the latest version of org.apache.sling.testing.paxexam .
Examples:

Failure with OSGi Converter
Symptom: Test execution leveraging the OSGi converter implementation fails with error messages like org.osgi.util.converter.ConversionException: Cannot convert 1234 to class java.lang.Integer
Remediation: Update to newer version of OSGi converter ( FELIX-6157 - Getting issue details... STATUS ). The converter impl from Felix was migrated to OSGi and should be referenced with coordinates
<dependency>
<groupId>org.osgi</groupId>
<artifactId>org.osgi.util.converter</artifactId>
<version>1.0.9</version>
</dependency>
The newest version is exporting still the original package version therefore referencing the newest 1.0.x version does not affect backwards-compatibility at run time.
Examples:
- SLING-11880 - Getting issue details... STATUS
