Improve error message for JPA: Generate Entities From Table ----------------------------------------------------------- Key: FORGE-2669 URL: https://issues.jboss.org/browse/FORGE-2669 Project: Forge Issue Type: Bug Components: Database Tools Affects Versions: 3.2.2.Final Environment: FC24 Red Hat JBoss Developer Studio Version: 10.0.1.AM2 Build id: AM2-v20160712-2233-B5658 Build date: 20160712-2233 Reporter: Josef Kopriva Assignee: George Gastaldi Priority: Minor Fix For: 3.2.3.Final Error message when generating JPA entities is not explaining what can be wrong (java.lang.IllegalArgumentException: Error Message cannot be null). 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}
