Hello
After days of investigations I narrowed the problem down to Blob fields.
I created the following test code in a controller.
Code:
private String path = "testdir/test6.log";
private String content = path;
@RequestMapping(value = "/update/test6", method = RequestMethod.GET)
@Transactional(propagation = Propagation.REQUIRED, rollbackFor = Exception.class)
public void test6(Writer writer) throws Exception {
try {
IEntityManagerService entityManagerService = CommonPlugin.getService(IEntityManagerService.class);
EntityManager entityManager = entityManagerService.getEntityManager();
Session session = (Session) entityManager.getDelegate();
RepositoryEntry entry = SoftmodelerFactory.eINSTANCE.createRepositoryEntry();
entry.setId(IdUtil.generateUUID(entry.eClass()));
entry.setModifyDate(new Date());
entry.setType("data");
entry.setPath(path);
entry.setData(session.getLobHelper().createBlob(content.getBytes()));
session.merge(entry);
writer.append("Entry ID: ").append(entry.getId());
} catch (Exception e) {
e.printStackTrace();
}
}
@RequestMapping(value = "/update/test7", method = RequestMethod.GET)
@Transactional(propagation = Propagation.REQUIRED, rollbackFor = Exception.class)
public void test7(Writer writer) throws Exception {
try {
IEntityManagerService entityManagerService = CommonPlugin.getService(IEntityManagerService.class);
EntityManager entityManager = entityManagerService.getEntityManager();
Session session = (Session) entityManager.getDelegate();
Criteria criteria = session.createCriteria(RepositoryEntry.class);
criteria.add(Restrictions.eq("path", path));
RepositoryEntry entry = (RepositoryEntry) criteria.uniqueResult();
entry.setModifyDate(new Date());
session.merge(entry);
writer.append("Entry ID: ").append(entry.getId());
} catch (Exception e) {
e.printStackTrace();
}
}
First I call "/update/test6" to create the repository entry object. I then call "/update/test7" and it may work first, but after at least 3 executions I get the following exception:
Code:
WARN: Transaction - Unexpected exception from beforeCompletion; transaction will roll back

The problem seems to occure because of the RepositoryEntry.data field which is a Blob and only if it contains content.
If I remove this line in test6(),
"entry.setData(session.getLobHelper().createBlob(content.getBytes()));"
no exception is thrown after lots of update/test7 calls.
Can somebody verify this as bug?
