Hibernate bug, how to workaround?

Question

I use Hibernate 3.5.3, and Oracle 10g database

I have bean with following relation

@OneToMany
@JoinTable(name="dispenser_accounts",
        joinColumns=@JoinColumn(name="terminal_id"), 
        inverseJoinColumns=@JoinColumn(name="dispenser_section_id"))
@MapKey(name="dispenserNumber")
private Map<Integer, DispenserAccount> activeDispensers = new HashMap<Integer, DispenserAccount>();

When I trying to fetch data from activeDispensers hibernate generate sql with wrong syntax

SQL Error: 907, SQLState: 42000
ORA-00907: missing right parenthesis

How to workaround this bug?

Thanks!
