[radovanradic]

An exception is thrown when trying to load multiple entities with embedded ids:

Please have a look at the reproducer example attached hibernate-reactive-embeddedid-issue.zip Uncompress it and run ./gradlew run and see the exception being thrown.

Please note if dependencies are changed to

implementation 'org.hibernate:hibernate-core:6.5.2.Final'
implementation 'org.hibernate.reactive:hibernate-reactive-core:2.3.1.Final'

then the exception is not being thrown.
