Stackoverflow error on merge

Hibernate ORM
1

Hello,

We have an entity which refers other entities with OneToOne and OneToMany relationships. Of late we are getting java.lang.StackOverflowError on merge.

Brief stack of error is as

Caused by: java.lang.StackOverflowError
	at org.hibernate.service.internal.SessionFactoryServiceRegistryImpl.getService(SessionFactoryServiceRegistryImpl.java:80) ~[hibernate-core-5.2.17.Final.jar:5.2.17.Final]
	at org.hibernate.engine.jdbc.internal.StatementPreparerImpl.getJdbcService(StatementPreparerImpl.java:205) ~[hibernate-core-5.2.17.Final.jar:5.2.17.Final]

	at org.hibernate.engine.jdbc.internal.StatementPreparerImpl$StatementPreparationTemplate.prepareStatement(StatementPreparerImpl.java:166) ~[hibernate-core-5.2.17.Final.jar:5.2.17.Final]

Any pointers on this would be helpful.

Thanks in Advance.

Best
