We have a Java EE JSP Application running on a tomcat 6 Server. We integrated the BIRT Viewer (2.6) using the <birt:viewer> - Taglib.
A month ago we updated our test system to BIRT 3.7RC1 to fix a bug in the drill down reports. Everything worked fine.
With the final version 3.7.0, none of our reports works. "Unknown Error"

the console log shows the following:
java.lang.NullPointerException

After some debugging i figured out an issue in the class org.eclipse.birt.report.engine.api.impl.EngineTask in line 240. The constructor of the class ExecutionContext seems not to be called, no idea why.

In the preview of the Report Designer the reports are shown correctly.

Reproducible: Always
