 <p>JMS cache coordination is always asynchronous, regardless of this setting.</p>
 <p>By default, RMI cache coordination is asynchronous. Use synchronous (<code>eclipselink.cache.coordination.propagate-asynchronously</code> = <code>false</code>) to ensure that all servers are updated before the request returns.</p>

 <p><strong><br /><span class="refsubsect">Usage</span></strong></p>
 <p>Form a property name by appending either a valid entity name or class name to <code>cache.size</code>, indicating that the property values apply only to a particular entity. As an alternative, you can append the <code>default</code> suffix to the <code>cache.size</code> property prefix, indicating that the property value applies to all entities.</p>
 <p>For most cache types, the size is only the initial size, not a fixed or maximum size. For <code>CacheType.SoftCache</code> and <code>CacheType.HardCache</code> types, the size is the sub-cache size. The default cache size is 100 Bytes.</p>
