Rick Curtis created OPENJPA-2493: ------------------------------------ Summary: SQLException while processing a query result Key: OPENJPA-2493 URL: https://issues.apache.org/jira/browse/OPENJPA-2493 Project: OpenJPA Issue Type: Bug Components: kernel, query Affects Versions: 2.2.2, 2.3.0 Reporter: Rick Curtis
I encountered a bug in a test environment that I wanted to open so I don't forget about it. My best guess is that this bug is somewhere in one of the query / sql caches. It looks very similar to OPENJPA-2482, but it is indeed different. Attached below is a multithreaded test that is able to recreate the stacktrace below 75% of the time. <openjpa-0.0.0-rnull nonfatal general error> org.apache.openjpa.persistence.PersistenceException: org.apache.openjpa.jdbc.kernel.exps.Count@336eb7fc FailedObject: SELECT b.oid, COUNT(b) FROM Book b where b.dueDate BETWEEN :start AND :end GROUP BY b.oid [java.lang.String] at org.apache.openjpa.jdbc.sql.DBDictionary.narrow(DBDictionary.java:5008) at org.apache.openjpa.jdbc.sql.DBDictionary.newStoreException(DBDictionary.java:4968) at org.apache.openjpa.jdbc.sql.SQLExceptions.getStore(SQLExceptions.java:135) at org.apache.openjpa.jdbc.sql.SQLExceptions.getStore(SQLExceptions.java:116) at org.apache.openjpa.jdbc.sql.SQLExceptions.getStore(SQLExceptions.java:68) at org.apache.openjpa.jdbc.kernel.SelectResultObjectProvider.handleCheckedException(SelectResultObjectProvider.java:155) at org.apache.openjpa.kernel.QueryImpl$PackingResultObjectProvider.handleCheckedException(QueryImpl.java:2111) at org.apache.openjpa.lib.rop.EagerResultList.<init>(EagerResultList.java:40) at org.apache.openjpa.kernel.QueryImpl.toResult(QueryImpl.java:1251) at org.apache.openjpa.kernel.QueryImpl.execute(QueryImpl.java:1007) at org.apache.openjpa.kernel.QueryImpl.execute(QueryImpl.java:863) at org.apache.openjpa.kernel.QueryImpl.execute(QueryImpl.java:794) at org.apache.openjpa.kernel.DelegatingQuery.execute(DelegatingQuery.java:542) at org.apache.openjpa.persistence.QueryImpl.execute(QueryImpl.java:275) at org.apache.openjpa.persistence.QueryImpl.getResultList(QueryImpl.java:291) at org.apache.openjpa.persistence.jdbc.sqlcache.TestMultiThreadedQuery$Worker.run(TestMultiThreadedQuery.java:94) Caused by: java.sql.SQLException: org.apache.openjpa.jdbc.kernel.exps.Count@336eb7fc at org.apache.openjpa.jdbc.sql.SelectImpl$SelectResult.findObject(SelectImpl.java:2512) at org.apache.openjpa.jdbc.sql.ResultSetResult.translate(ResultSetResult.java:497) at org.apache.openjpa.jdbc.sql.ResultSetResult.getObjectInternal(ResultSetResult.java:362) at org.apache.openjpa.jdbc.sql.AbstractResult.getObject(AbstractResult.java:691) at org.apache.openjpa.jdbc.kernel.exps.UnaryOp.load(UnaryOp.java:120) at org.apache.openjpa.jdbc.kernel.ProjectionResultObjectProvider.getResultObject(ProjectionResultObjectProvider.java:78) at org.apache.openjpa.kernel.QueryImpl$PackingResultObjectProvider.getResultObject(QueryImpl.java:2075) at org.apache.openjpa.lib.rop.EagerResultList.<init>(EagerResultList.java:36) ... 8 more -- This message was sent by Atlassian JIRA (v6.2#6252)
