> An odd problem happens when building on Jenkins. E.g. this build (Java 7, HSQLDB) :
> https://builds.apache.org/job/Cayenne-trunk/cayenneTestConnection=HSQLDB,jdk=JDK%201.7%20%28latest%29,label=Ubuntu/781/
> results in the following exception:
> -------------------------------------------------------------------------------
> Test set: org.apache.cayenne.access.NestedDataContextWriteTest
> -------------------------------------------------------------------------------
> Tests run: 11, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 0.151 sec <<< FAILURE!
> testAddRemove(org.apache.cayenne.access.NestedDataContextWriteTest) Time elapsed: 0.012 sec <<< ERROR!
> java.lang.NullPointerException
> at org.apache.commons.collections.map.AbstractReferenceMap$ReferenceEntry.getValue(AbstractReferenceMap.java:597)
> at org.apache.commons.collections.map.AbstractReferenceMap.get(AbstractReferenceMap.java:234)

> at org.apache.cayenne.access.DataContext.flushToParent(DataContext.java:771)
> at org.apache.cayenne.access.DataContext.commitChanges(DataContext.java:697)
> at org.apache.cayenne.access.NestedDataContextWriteTest.testAddRemove(NestedDataContextWriteTest.java:632)
> The code is as vanilla and single threaded as it gets:
> DataContext context = createDataContext();
> ObjectContext child = runtime.getContext(context);
> Artist a = child.newObject(Artist.class);
> a.setArtistName("X");
> child.commitChanges(); // this is line 632 that causes exception
> It appears that ObjectStore.objectMap somehow gets corrupted... Sure enough it is only reproducible on Jenkins, and never - locally.
