These issues affect installation on all platforms.
The Ready to Install screen displays the product name as “mq” rather than as Sun Java System Message Queuye 4.2. (Bug 6650841)
When the Installer is in the process of installing Message Queue 4.2 and the Progress screen is displayed, the Cancel button is active. Selecting the Cancel button at this time results in incomplete or broken installs. (Bug 6595578)
The Installer Summary Screen contains a number of links that when clicked will launch a log or summary page viewer. If you dismiss this viewer window using the window close button “X” instead of the button labelled “close', you will not be able to bring this viewer window back up. (Bug 6587138)
Workaround: Use the button labeled Close to close the window.
When a computer system has older versions of Message Queue and NSS/NSPR, the installer's Upgrade screen only lists Message Queue as requiring upgrade; it does not mention that NSS and NSPR need to be upgraded as well. All the relevant software will nevertheless be upgraded (as indicated by The ReadyToInstall screen which shows the correct information). (Bug 6580696)
List of JDKs on JDK Selection Screen is active even when “Choose a JDK” option is not selected. (Bug 6650874)
