If any Java project in the workspace has missing "output" entry in .classpath file, opening an existing data set in Report Designer will result in NPE:

Reproducible: Always

Steps to Reproduce:
1. Create a Java project that does not have source code and make sure "output" entry is not in .classpath file.
2. Open existing BIRT report in Report Designer. 
3. Click on existing data set. NPE will be thrown.
