This error occurs only some of the time, which leads me to believe there is a
threading issue here. Specifically, looking at the following code fragment in
{{org.apache.openejb.core.stateless.StatelessInstanceManager.getInstance(StatelessInstanceManager.java:111)}}:
{code}
Context ctx = deploymentInfo.getJndiEnc();
SessionContext sessionContext;
try {
sessionContext = (SessionContext)
ctx.lookup("java:comp/EJBContext");
} catch (NamingException e1) {
sessionContext = createSessionContext();
// TODO: This should work
ctx.bind("java:comp/EJBContext", sessionContext);
}
{code}
It could be perhaps that the "java:/comp/EJBContext" is not initially found,
but another thread creates it by the time it is attempted to be bound in the
last line. Unfortunately, I do not have a reproducible test case at the
current time.
