Re: EhCache Java11 ( https://hibernate.atlassian.net/browse/HHH-13503?atlOrigin=eyJpIjoiMThjZDY1ZDVkMTcxNDliMmJkZDFiNTVjNWM2MDc5Y2IiLCJwIjoiaiJ9 )

I have encountered the same issue using java 8, hibernate 5.4.15 and EhCache 3.8.1 as a second level cache.

I've tracked it down by activating the sun.io.serialization.extendedDebugInfo property, which gives the SerializationTrace.txt ( https://hibernate.atlassian.net/secure/attachment/49683/49683_SerializationTrace.txt ) attached

In short, here's what I found:

* The result query cache doesn't work with queries using named parameters on fields which are typed using a javax.persistence.Convert converter
* This is because the the resolved type which is stored inside org.hibernate.cache.spi.QueryKey is an instance of org.hibernate.type.descriptor.converter.AttributeConverterSqlTypeDescriptorAdapter which is not serializable.
* When the key is then stored inside EhCache, it throws the NotSerializableException

I'm reasonably certain that this is not a regression, but something that surfaced when moving to EhCache 3 (never had any issues with EhCache 2)

What I do for now is to disable the result cache for these queries, but I have no real solutions. Any ideas?
