        Key: HB-127
    Summary: CounterGenerator Bug
       Type: Bug

     Status: Unassigned
   Priority: Major

    Project: Hibernate2
 Components: 
             core
   Versions:

    Updated: Tue, 10 Jun 2003 8:23 AM
Environment: Sybase 11.9.2

Description:
When using "vm" generator, experiencing problem of trying to insert a non-unique value of PK. 

When sleep() inserted in generate() (just for test purposes), problem disappeared.

So, with minor changes:

	private static long counter =  0;

	protected long getCount() {
		synchronized(CounterGenerator.class) {
			if (counter==0) counter=System.currentTimeMillis();
			return counter++;
		}
	}

	public Serializable generate(SessionImplementor cache, Object obj) {
		return new Long( getCount() );
	}

problem has been resolved.

please.. do something more serious about it :)
