Symptoms

Configuring a fresh Bamboo installation fails with following exception:

java.lang.IllegalStateException: Cannot initialize context because here is already a root application context present - check whether you have multiple ContextLoader* definitions in your web.xml

Causes

1. The database selection is changed half way through the setup process.
2. If the Next button is clicked twice.

Resolution

The only workaround is to shutdown Bamboo, delete BAMBOO_HOME and start over.
