[jboss-user] [EJB/JBoss] - JBoss 4.3 - Entity Beans Reentrant behavior

[rksavvion]

Presently for our EJB application, we have REENTRANT  as false for the Entity beans (ejb 2.1) and performance test involving higher concurrency pose no problem for JBoss 5 (as well as for weblogic, websphere). 

However, for JBoss 4.3, with REENTRANT as false for Entity beans, 
following exception occurs for higher concurrency.
TransactionRolledbackLocalException: Reentrant method call detected

Setting the REENTRANT behavior to TRUE solves this problem and there are no "Reentrant method call detected" exception.

Any suggestions or documentation suggesting the pros/cons of setting the 
Entity Beans Reentrant behavior to TRUE is appreciated.

Stack trace:
javax.ejb.TransactionRolledbackLocalException: Reentrant method call detected: ProcessInstanceEBBBean 4808
