I've reproduced initial problem. Following method is test which fails:
public void testRemoveVersionInTxThreeTransactions() {
final String v1 = (String) transactionTemplate.execute(new
TransactionCallback() {
public Object doInTransaction(TransactionStatus status) {
return (String) jcrTemplate.execute(new JcrCallback() {
public Object doInJcr(Session session) throws
IOException,
RepositoryException {
Node target =
session.getRootNode().addNode("target3");
target.addMixin("mix:versionable");
session.save();
VersionHistory vh = target.getVersionHistory();
Version v1 = target.checkin();
return v1.getName();
}
});
}
});
final String v2 = (String) transactionTemplate.execute(new
TransactionCallback() {
public Object doInTransaction(TransactionStatus status) {
return jcrTemplate.execute(new JcrCallback() {
public Object doInJcr(Session session) throws
IOException,
RepositoryException {
Node target =
session.getRootNode().getNode("target3");
VersionHistory vh = target.getVersionHistory();
target.checkout();
Version v2 = target.checkin();
return v2.getName();
}
});
}
});
transactionTemplate.execute(new TransactionCallback() {
public Object doInTransaction(TransactionStatus status) {
jcrTemplate.execute(new JcrCallback() {
public Object doInJcr(Session session) throws
IOException,
RepositoryException {
Node target =
session.getRootNode().getNode("target3");
VersionHistory vh = target.getVersionHistory();
target.restore(v1, true);
vh.removeVersion(v2);
return null;
}
});
return null;
}
});
}
Following exception is thrown:

In this test, node is created and checked-in in first transaction, then
checked-out and checked-in in second transaction (so second version is
created), then node is restored to version 1 and its last version (version
2) is tried to be removed in third transaction - which fails.
If we put creation of second version, node restore and removal of first
version in one transaction, test does not fail.
