On app restart, during a bean initialization method, an entity is loaded from second level cache, and AttributeConverter fails with ClassCastException.
URLImpl class extends URL interface. Entity has a URL member.

Comment From: wilkinsona
You've ended up with an instance of myapp.util.web.URLImpl that was loaded from one iteration of your app and its interface, myapp.util.web.URL, loaded from another. That's probably due to how the instance is being retrieved from the second-level cache but I can't say for sure as you haven't shown how that's being done.
If you would like us to spend some more time investigating, please spend some time providing a complete yet minimal sample that reproduces the problem. You can share it with us by pushing it to a separate repository on GitHub or by zipping it up and attaching it to this issue.
Comment From: cdalexndr
Sample repository: https://github.com/cdalexndr/spring-boot-issue-23729
Reproduction steps: 1. gradlew bootRun //generates disk cache 2. stop app 3. gradlew bootRun 4. edit ./build/resources/trigger.txt to trigger app restart 5. exception
Comment From: snicoll
Thanks for the sample. @wilkinsona already explained what is going on.
That's probably due to how the instance is being retrieved from the second-level cache
This section of the reference guide describes how to configure devtools so that objects that are persisted to disk can be safely restored across restarts.
I've included ehcache to the restart classloader and the exception described above went away. Unfortunately, ehcache now complains that the persistence directory is already locked by this process:

I am afraid we can't provide you support for the ehcache issue. I would personally fallback on a much simpler cache arrangement while developing in the IDE, this StackOverflow answer provides some more details.
