Excelsior JET 3.7 Maintenance Pack 3 Download

NOTE: This Maintenance Pack has been superceded by Maintenance Pack 4, which is now the recommended download.

Excelsior JET 3.7 Maintenance Pack 3 (MP3) is an optional update that fixes multiple customer issues and adds support for J2SE 5.0 Update 3 (1.5.0_03), 5.0 Update 4 (1.5.0_04), and 1.4.2_08. It supersedes Maintenance Pack 2 and incorporates all hotfixes you may have received from Excelsior Technical Support prior to October 5, 2005.

In particular, MP3 fixes a number of incompatibilities with the newest Linux kernel revisions (2.6.12 and above) and rapidly evolving distributions such as Fedora Core. Installation of MP3 is therefore mandatory if you use Excelsior JET on such a system and/or optimize applications that will be deployed on such systems.

WARNING: Maintenance Packs fix particular problems reported by Excelsior JET users and discovered by Excelsior test engineers after the release of the respective version of the product. They are tested on a representative subset of the test suite used during preparation of the original release. We therefore only recommend you to install Maintenance Packs in the following cases:

You have been advised to do so by an Excelsior support engineer;
You need to switch to a Java SE (micro)version supported through a Maintenance Pack;
You want to try a new technology from Excelsior that requires installation of a particular Maintenance Pack; or
You are experiencing a severe problem, such as compiler or application crash or incorrect application behavior.

Depending on the platform and Excelsior JET Edition you are using, click one of the download links below:

Platform	Edition	Download
Windows	Professional	jet-370-mp3-pro-en-win32.exe
Windows	Standard	jet-370-mp3-std-en-win32.exe
Linux	Professional	jet-370-mp3-pro-en-linux.bin
Linux	Standard	jet-370-mp3-std-en-linux.bin

Installation Instructions

MP3 installs on top of the original Excelsior JET 3.7, possibly with previous Maintenance Packs and/or hotfixes applied. If you need to make a fresh installation, install Excelsior JET 3.7 first, cancel JET Setup, apply MP3, and then use JET Setup to create profiles.

To update an existing Excelsior JET installation, launch the downloaded executable and follow the on-line prompts. Upon successful copying of Maintenance Pack files, JET Setup will launch automatically and apply the Maintenance Pack.

Note: Installation of MP3 obsoletes your current JET profiles, if any. Those profiles will be backed up by JET Setup. If you rollback to the previous update level, they will be restored.

Update Management

Windows

To rollback to the previous update level, select Manage JET Updates in Excelsior JET Start Menu and click Undo.

Rollback does not remove the installed updates and associated profiles, so you can reapply MP3 later without installing it. Select Manage JET Updates and click Redo until it displays the current configuration as "jet-370-mp3".

Linux

Run JET Setup to display the list of installed updates: jetsetup -show-updates
Locate in the list the updates which you need to activate. Then run JET Setup again as follows: jetsetup -activate-update list
where list is a colon-separated list of update names.
Display the list of profiles available for the new combination of updates: jetsetup -show-profiles
If necessary, create new profiles.
