Created attachment 129952 [details] Log file INFO [org.netbeans.modules.j2ee.jpa.verification.JPAProblemFinder]: NPE in jpql validation: null java.lang.NullPointerException at org.netbeans.modules.j2ee.persistence.spi.jpql.ManagedTypeProvider.getManagedType(ManagedTypeProvider.java:102)
it's expected behavior, there may be some cases unsupported by 3rd party library, and in general the only general solution to log with level fine instead of info later (or may be never to track valid cases more easily). but some specific cases may be valid issues, and need to be filed separately with more details. required details is jpql query string at least, if with cc then cursor position, and better if full project or some details on existent and mossed entities and relationships.
This old bug may not be relevant anymore. If you can still reproduce it in 8.2 development builds please reopen this issue. Thanks for your cooperation, NetBeans IDE 8.2 Release Boss
