Excelsior JET 4.8 Maintenance Pack 1 Download

NOTE: This Maintenance Pack has been superceded by Maintenance Pack 3, which is now the recommended download.

Excelsior JET 4.8 Maintenance Pack 1 (MP1) is a highly recommended update that fixes multiple customer issues. It incorporates all hotfixes you may have received from Excelsior Technical Support prior to December 15, 2006.

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.

Update Management

Locate in the list the updates which you need to activate. Then run JET Setup again as follows:
