Show original exception instead of NullPointerExcetpion from TransactionHandler ------------------------------------------------------------------------------- Key: ARQ-1842 URL: https://issues.jboss.org/browse/ARQ-1842 Project: Arquillian Issue Type: Sub-task Components: Base Implementation Reporter: Alexandr Sokolov Fix For: 2.0.0.CR1 Arquillan architecture based on observers. But now, if one of observers throws an exception and transactions are used. We are getting: java.lang.NullPointerException: null at org.jboss.arquillian.transaction.impl.lifecycle.TransactionHandler.testRequiresRollbackDueToFailure(TransactionHandler.java:170) Although the actual exception in my case was thrown by DBUnitDataHandler.prepare(). Could you please change the logic so the original exception is displayed in the output? Otherwise we have to debug to get the actual exception. There is no way to find a solution without debugging via arquillian classes. It really takes rather long time.
