Expected Results

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.
