My application works perfect with 1.4.0.SP1 but not with 1.4.1.GA. I have got
node " / a / b"
Everything works fine then I remove (TreeCacheMBean.remove(Fqn root);) then I
once again put " / a / b" (TreeCacheMBean.put(Fqn fqn, String key, Object
object);) and here problem starts. I have debugged a litle and found
problematic place: org.jboss.cache.interceptors.PessimisticLockInterceptor line
170
| (...)
| if (createIfNotExists)
| {
| do
| {
| lock(fqn, ctx.getGlobalTransaction(), lock_type, recursive,
zeroLockTimeout ? 0 : lock_timeout, createIfNotExists, storeLockedNode);
| }
| while(!cache.exists(fqn)); // keep trying until we have the
lock (fixes concurrent remove())
| // terminates successfully, or with (Timeout)Exception
| }
|
| (...)
|
cache.exists(fqn) always returns false beause node "a" in fqn " / a / b"
has been marked for removal (data={__JBOSS_MARKED_FOR_REMOVAL=null})
and org.jboss.cache.Node.getOrCreateChild(..) (line 322) does nothing with this
node because it only creates new node if children().get(child_name)==null but
this node is not null ! it exists and has __JBOSS_MARKED_FOR_REMOVAL flag.
Why node 'a' is not removed but only marked __JBOSS_MARKED_FOR_REMOVAL?
It is connected with JBCACHE-871 ?
My TransactionManager configuration:
<attribute name="TransactionManagerLookupClass">
| org.jboss.cache.JBossTransactionManagerLookup
| </attribute>

| <attribute name="IsolationLevel">NONE</attribute>
