Hibernate ORM 5.2 is not compatible with any version of Hibernate Search, including 5.6.0.Beta1 since all version of Hibernate Search are compiled with previuos version of Hibernate ORM. This is making Hibernate ORM 5.2 impossible to use in any project that is using Hibernate Search.

Example:

ava.lang.NoSuchMethodError caught: java.lang.NoSuchMethodError: org.hibernate.event.spi.EventSource.getTransactionCoordinator()Lorg/hibernate/resource/transaction/TransactionCoordinator;
at org.hibernate.search.backend.impl.EventSourceTransactionContext.isLocalTransaction(EventSourceTransactionContext.java:117)
at org.hibernate.search.backend.impl.EventSourceTransactionContext.registerSynchronization(EventSourceTransactionContext.java:84)
