I get java.lang.NullPointerException error in Studio


I get an error when trying to preview data (under Dataset and query)

at com.jaspersoft.studio.data.reader.DatasetReader.start(DatasetReader.java:187)
at com.jaspersoft.studio.property.dataset.dialog.DataPreviewTable$4.run(DataPreviewTable.java:247)
at org.eclipse.core.internal.jobs.Worker.run(Worker.java:54)
I am using a oracle driver (ojdbc6.jar). If I were to change the SQL to a simple query (select * from dual) it works. when trying a SQL with joined tables, I get that error.
My coworker who has the same exact configuration (DB, driver, OS) get the SQL to run no problem.
Any suggestions?
