I have a problem of startup with eclipselink when i start my program with JRE up to 6u18 in an application Java Web Start.

With JWS with the JRE even the version 6u17 the istruction 
Persistence.createEntityManagerFactory("TEST")

use about 1 second, with JRE 6u21 use 1 minute and 13 second

The istruction 
em = emf.createEntityManager();
use about 2 second with JRE even 6u17, and use 1 minute and 9 second with JRE 6u21

This happen only at first use of this istruction.

What's the problem?

Sounds like a JRE and Java WebStart issue, you could try asking for help in another forum.

Can you profile the application as see where to time is being spent?
