This is related to hibernate-tools core.
Bad things which I have found:
1. @Table annotation - closing bracket on new line
2. @ManyToOne has no intend on the left
3. Class fields have 5 spaces indent on the left
4. Fields assignments in constructor have 3 spaces indentation
5. No empty line between constructors with arguments and 2 empty lines after default constructor
6. Redundant empty line before @Column
7. Redundant 2 empty lines before class close brace
8. 5 spaces before @Id
