OutOfMemoryError: Java heap space with @ManyToOne(fetch = FetchType.EAGER) after Migrating to spring boot 3.2;Hibernate 6.3

Question

if I set @ManyToOne(fetch = FetchType.LAZY) it is working. In my case I need EAGER loading. But this leads to the OutOfMemoryError. Even if they increase the in maven memory, it does not work:
