High Issue Summary
Similar to Search via REST API might fail due to ClassCastException, ServiceDesk can cause class cache exceptions while fetching customer requests using GET /rest/servicedeskapi/request.
com.atlassian.crowd.exception.DirectoryInstantiationException: com.atlassian.cache.CacheException: com.atlassian.cache.CacheException: com.atlassian.crowd.exception.DirectoryInstantiationException: java.lang.ClassCastException: class org.springframework.core.convert.support.DefaultConversionService cannot be cast to class org.springframework.core.convert.support.GenericConversionService (org.springframework.core.convert.support.DefaultConversionService is in unnamed module of loader org.apache.felix.framework.BundleWiringImpl$BundleClassLoader @52da1cfd; org.springframework.core.convert.support.GenericConversionService is in unnamed module of loader org.apache.catalina.loader.ParallelWebappClassLoader @1a717d79) at com.atlassian.crowd.directory.loader.CacheableDirectoryInstanceLoader.getDirectory(CacheableDirectoryInstanceLoader.java:83) at com.atlassian.crowd.manager.directory.DirectoryManagerGeneric.getDirectoryImplementation(DirectoryManagerGeneric.java:296) at com.atlassian.crowd.manager.directory.DirectoryManagerGeneric.findUserByName(DirectoryManagerGeneric.java:317) at com.atlassian.crowd.manager.application.canonicality.CanonicalEntityByNameFinder.findByName(CanonicalEntityByNameFinder.java:109) at com.atlassian.crowd.manager.application.canonicality.CanonicalEntityByNameFinder.findByName(CanonicalEntityByNameFinder.java:95) at com.atlassian.crowd.manager.application.canonicality.CanonicalEntityByNameFinder.findUserByName(CanonicalEntityByNameFinder.java:79) at com.atlassian.crowd.manager.application.ApplicationServiceGeneric.findUserByName(ApplicationServiceGeneric.java:319) at com.atlassian.crowd.embedded.core.CrowdServiceImpl.getUser(CrowdServiceImpl.java:86) ... java.lang.ClassCastException: class org.springframework.core.convert.support.DefaultConversionService cannot be cast to class org.springframework.core.convert.support.GenericConversionService (org.springframework.core.convert.support.DefaultConversionService is in unnamed module of loader org.apache.felix.framework.BundleWiringImpl$BundleClassLoader @189c585e; org.springframework.core.convert.support.GenericConversionService is in unnamed module of loader org.apache.catalina.loader.ParallelWebappClassLoader @1a717d79)
Steps to Reproduce
No particular steps could be identified, the issue is happening at random.
Expected Results
No class cast exceptions should be thrown and requests should be served.
Actual Results
The below exception is thrown in the xxxxxxx.log file:
com.atlassian.crowd.exception.DirectoryInstantiationException: java.lang.ClassCastException: class org.springframework.core.convert.support.DefaultConversionService cannot be cast to class org.springframework.core.convert.support.GenericConversionService (org.springframework.core.convert.support.DefaultConversionService is in unnamed module of loader org.apache.felix.framework.BundleWiringImpl$BundleClassLoader @189c585e; org.springframework.core.convert.support.GenericConversionService is in unnamed module of loader org.apache.catalina.loader.ParallelWebappClassLoader @1a717d79)
Workaround
Rolling restart of the nodes helped in getting rid of these exceptions. But this workaround did not help all the time and multiple restarts are required.
