The Enterprise JavaBeans 3.0 core specification, Section 21.1.2, states:
|
|
</p>
|
|
|
|
<blockquote>
|
|
<p>
|
|
An enterprise bean must not use thread synchronization primitives to synchronize execution of
|
|
multiple instances.
|
|
</p>
|
|
<p>
|
|
Synchronization would not work if the EJB container distributed
|
|
enterprise bean's instances across multiple JVMs.
|
|
</p>
