Gail Badner resolved HHH-5534.
------------------------------
Resolution: Rejected
> 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: 3.6.1
>

> 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.
