Subject [jira] [Updated] (OPENEJB-2119) Incorrect binary tree - IvmContext
Date Fri, 16 Oct 2015 15:03:05 GMT

     [ https://issues.apache.org/jira/browse/OPENEJB-2119?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Milos Volauf updated OPENEJB-2119:
----------------------------------
    Description: 
I get many javax.naming.NameAlreadyBoundException exceptions so I digged into org.apache.openejb.core.ivm.naming.IvmContext
and org.apache.openejb.core.ivm.naming.NameNode.

I was strange that NameAlreadyBoundException was fired from IvmContext.rebind, which does
unbind and then bind.
The debugging showed me that binary tree (implemented by NameNode) gets sometimes into incorrect
state and consequently unbind does not find the node.

The problem is that IvmContext has a reference to NameNode and calls bind() but the binary
tree is correct only if bind() starts at the tree root. There is one big tree and several
contexts have their nodes in it (IvmContext.mynode) and bind new nodes starting in mynode.

I prepared a small test case which shows how the tree can enter into incorrect state.

I used openejb-core-4.7.1

  was:
