Regression in 3.5.5: Cascade on merge for Sets fails with transient
entities
-----------------------------------------------------------------------------
Key: HHH-5534
URL:
http://opensource.atlassian.com/projects/hibernate/browse/HHH-5534
Project: Hibernate Core
Issue Type: Bug
Components: core
Affects Versions: 3.5.5
Environment: Hibernate 3.5.5, Oracle 10g.
Reporter: Kyrill Alyoshin
Assignee: Gail Badner
Fix For: 3.5.6, 3.6.x
Something happened from 3.5.4 to 3.5.5. Here is regression issue we're experiencing
after upgrade:
We have entities ResearchClientFile and ResearchVendorRecord.
RCF maps RVR:
@Sort(type = SortType.NATURAL)
@OneToMany(mappedBy = "file", fetch = FetchType.LAZY, cascade =
CascadeType.ALL)
public SortedSet<ResearchVendorRecord> getRecords() {
return records;
}
RVR maps RCF:
@ManyToOne(fetch = FetchType.LAZY, optional = false)
@JoinColumn(name = "research_client_file_id")
public ResearchClientFile getFile() {
return file;
}
The following unit test:
ResearchClientFile rcf = RandomUtils.randomBean(ResearchClientFile.class);
rcf.addRecord(RandomUtils.randomBean(ResearchVendorRecord.class));
rcf = session.merge(rcf);
produces the following exception in 3.5.5 but not in 3.5.4.:
java.lang.NullPointerException: null entities are not supported by
org.hibernate.event.def.EventCache
at org.hibernate.event.def.EventCache.containsKey(EventCache.java:80)
at
org.hibernate.event.def.DefaultMergeEventListener.mergeTransientEntity(DefaultMergeEventListener.java:361)
at
org.hibernate.event.def.DefaultMergeEventListener.entityIsTransient(DefaultMergeEventListener.java:303)
at
org.hibernate.event.def.DefaultMergeEventListener.onMerge(DefaultMergeEventListener.java:258)
at org.hibernate.impl.SessionImpl.fireMerge(SessionImpl.java:869)
equals, hashCode and compareTo are completely consistent in RVR.
The issue seems to affects only Set and SortedSets and on merge only. Lists (with bag
semantics) do not appear to be affected on merge.
