In our latest Asset Bank 'quarterly' release we dropped support for Java 5 (installed on the server), so if you host your own Asset Bank and want to upgrade it to version 3.1370 or above you need to upgrade Java before upgrading Asset Bank.
Java 5 was released almost 10 years ago (back in 2004) and since then versions 6 and 7 have been released, bringing improved performance, new features and greater developer productivity. Dropping support for Java 5 enables us to benefit from this, and build high quality features more quickly.
If you host your Asset Bank with us you don't need to do anything, we are managing the upgrade of our hosting platform.
If you want to discuss this with us or want some help please get in touch with our support team.
