Steps to reproduce: 1. Create new project 2. Create connection profile (sakila) (do not check checkbox *Verify database connection*) - enter incorrect DB address 3. Create jboss data source 4. Crl+4 -> jpa-setup 5. Crl+4 -> jpa generate entities from tables - select sakila *Connection Profile* - first error occurs in Error Log: Unhandled event loop exception Stacktrace: {code:java}
