In org.hibernate.cache.spi.QueryKey there is a field org.hibernate.transform.CacheableResultTransformer which is not transient. It seems like this field is causing the exception. ehcach.xml <config xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance" xmlns= "http://www.ehcache.org/v3" xmlns:jsr107 = "http://www.ehcache.org/v3/jsr107" xsi:schemaLocation=" http://www.ehcache.org/v3 http://www.ehcache.org/schema/ehcache-core-3.0.xsd http://www.ehcache.org/v3/jsr107 http://www.ehcache.org/schema/ehcache-107-ext-3.0.xsd"> <service> <jsr107:defaults enable-management= "true" enable-statistics= "true" /> </service> <!-- cache eternal unless updated, i.e. no TTL from cache manager itself --> <cache-template name= "simple" > <expiry> <none/> </expiry> <heap unit= "entries" > 1000 </heap> </cache-template> <cache alias= "org.hibernate.cache.internal.StandardQueryCache" uses-template= "simple" /> <cache alias= "org.hibernate.cache.spi.TimestampsCache" uses-template= "simple" /> </config> ( https://hibernate.atlassian.net/browse/HHH-16684#add-comment?atlOrigin=ey... ) Add Comment ( https://hibernate.atlassian.net/browse/HHH-16684#add-comment?atlOrigin=ey... ) Get Jira notifications on your phone!
