You might want to review how ThreadLocal variables are implemented, though ... it's most likely to be some sort of HashMap keyed by classloader, and the get/put operations to update your thread's local copy are likely to be synchronized internally. The best way to avoid synchronization is likely to create one in a local variable, then pass it around to whomever needs it. Ugly, but performance hacks are sometimes like that. > -- > Martin Cooper Craig --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
