NullPointerException occurs when clicking Download link for new version

When presented with "Available Updates" dialog, clicking on "Download" link for version 720.1640 results in NullPointerException. This occurs immediately after starting the application, without any DB connections active. It occurs regardless of whether the "Available Updates" dialog is displayed because of an automatic check at startup or as a result of a manual update check. It seems 100% reproducible. Thanks. ------------------------- Product Information ------------------------ Product: DbVisualizer Personal 720.1638 Build: #1638 (2011/05/02 13:47) Java VM: Java HotSpot(TM) Client VM Java Version: 1.6.0_23 Java Vendor: Sun Microsystems Inc.
