I created a Stardust utility project with a Maven configuration. The project is connected to a Dynamic Web Project in Eclipse (via Deployment Assembly) to deploy it on a local Tomcat instance.
When running JUnit tests inside the utility project which bootstrap an IPP engine, the Derby EmbeddedDriver cannot be found even though it's declared as a Maven dependency and it's definitely on the classpath:
In the log the following exceptions appear:
Caused by: java.lang.NoClassDefFoundError: Could not initialize class org.apache.derby.jdbc.EmbeddedDriver
Caused by: java.lang.SecurityException: sealing violation: package org.apache.derby.impl.store.raw.data is sealed
