To replicate the issue, you can simply run the Unit Test contained in the attached Maven project:

There are two entities:

• Repository
• RepositoryWithExplicitCacheStrategy

Running the test:

doInTransaction(session ->

);
doInTransaction(session ->

);

Generates the following output:

Query:{[insert into Repository (id, name) values (default, ?)][Hibernate-Master-Class]} 
Query:{[insert into RepositoryWithExplicitCacheStrategy (id, name) values (default, ?)][RepositoryWithExplicitCacheStrategy]} 

Query:{[select defaultcac0_.id as id1_0_0_, defaultcac0_.name as name2_0_0_ from Repository defaultcac0_ where defaultcac0_.id=?][1]} 
Query:{[select defaultcac0_.id as id1_1_0_, defaultcac0_.name as name2_1_0_ from RepositoryWithExplicitCacheStrategy defaultcac0_ where defaultcac0_.id=?][1]} 

Query:{[select defaultcac0_.id as id1_0_0_, defaultcac0_.name as name2_0_0_ from Repository defaultcac0_ where defaultcac0_.id=?][1]} 

Only the RepositoryWithExplicitCacheStrategy gets cached because it has an explicit Cache Concurrency Strategy.
