A Thread

Answer 1

This is what I did to resolve this problem based on Spring Boot.

Solution

from

// application.properties  
spring.jpa.database-platform=org.hibernate.dialect.MySQLDialect

to

spring.jpa.database-platform=org.hibernate.dialect.MySQL5InnoDBDialect

Explanation
As you can see below, it seems like the default value for CascadeDelete at MySQL5InnoDBDialect.java only support Cascade.

// MySQLDialect.java
@Override
    public boolean supportsCascadeDelete() {
        return false;
    }

// MySQL5InnoDBDialect.java
@Override
    public boolean supportsCascadeDelete() {
        return true;
    }
