Excelsior JET 7.6 Hotfix 67

Note: This hotfix addresses a regression in Maintenance Pack 5. If you have installed MP5, projects in which the Global Optimizer is enabled may fail to build.

WARNING: Hotfixes address particular problems reported by Excelsior JET users and discovered by Excelsior test engineers between product and Maintenance Pack releases. They are only tested against the core test suite used during development and on the customer scenario(s), if any. We therefore only recommend you to install hotfixes in the following cases:

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