Subject [jira] Created: (JDO-640) NPE when running tck in debug mode
Date Fri, 11 Sep 2009 22:15:57 GMT
NPE when running tck in debug mode

                 Key: JDO-640
                 URL: https://issues.apache.org/jira/browse/JDO-640
             Project: JDO
          Issue Type: Bug
          Components: tck2
    Affects Versions: JDO 2 maintenance release 2
            Reporter: Michael Bouschen
            Assignee: Michael Bouschen

A couple of test configurations fail with a NPE when running the tck in debug mode, e.g.:

    [java] Caused by: org.springframework.beans.factory.BeanDefinitionStoreException: Factory
method [public org.apache.jdo.tck.pc.companyMapWithoutJoin.ICompany org.apache.jdo.tck.pc.companyMapWithoutJoin.CompanyFactoryAbstractImpl.newCompany(long,java.lang.String,java.util.Date)]
threw exception; nested exception is java.lang.NullPointerException

    [java]      at org.apache.jdo.tck.pc.companyMapWithoutJoin.Company.toString(Company.java:166)
    [java]      at java.lang.String.valueOf(String.java:2615)

    [java]      at org.apache.jdo.tck.pc.companyMapWithoutJoin.CompanyFactoryAbstractImpl.newCompany(CompanyFactoryAbstractImpl.java:55)

When running in debug mode the new Company method prints the created instance, before the
field values are initialized. So any date fields are still null and the code in getRepr runs
into the NPE for a null date field. 

To enable the debug mode, replace line
    log4j.logger.org.apache.jdo.tck = INFO, TCK
    log4j.logger.org.apache.jdo.tck = DEBUG, TCK
in file src/conf/log4j.properties.
