The following issues affect installation on the Linux Platform
On the JDK Selection panel, the scroll list displays only one item. This makes it difficult to select other JDK's in the list. (Bug 6584735)
If the JDK is current and the user selects “Install default JDK” on the JDK Selection Screen, the installer still tries to install it and reports that it cannot install the package. Installation completes successfully despite this issue. (Bug 6581310)
When the installer is run in dry run mode (installer –n), the Summary Screen shows some error messages and also displays an install status of “Incomplete”. This is incorrect and misleading; a dry run does not install anything on the system; it only creates the answer file that can be subsequently used to install.(Bug 6594351)
If older versions of Message Queue localization RPM's exist on your system, installation of Message Queue 4.1 localization RPM's (which happens when you select the “Install Message Queue multilingual packages” checkbox on the Multilingual Packages screen) will fail. Installation fails because of conflicts with Il8 packages from a previous 3.7 UR1 installation. (Bug 6594381)
Workaround Manually remove the localization RPM's using the rpm –e command before running the 4.1 Installer. To determine which RPM's are relevant here, see Message Queue Packages (RPMs) in Sun Java System Message Queue 4.1 Installation Guide.
