tapestry.thread-pool.max-pool-size not doing anything

Hi

I am using Tapestry 5.3.7 and the ParallelExecutor. When I increase the max-pool-size I am not able to use any more threads. However when I increase the core-pool-size I am able to use more threads. It looks like the max-pool-size is not doing anything (or I am not understanding what it is supposed to do).

When I use the defaults I get a maximum of 3 threads and other threads seem to wait in a queue and execute later.

When I use the following settings in web.xml I still get only 3 threads

<context-param>
<param-name>tapestry.thread-pool.core-pool-size </param-name>
<param-value>3</param-value>
</context-param>
<context-param>
<param-name>tapestry.thread-pool.max-pool-size</param-name>
<param-value>20</param-value>
</context-param>

When I use the following settings in web.xml I get 3 threads

<context-param>
<param-name>tapestry.thread-pool.core-pool-size </param-name>
<param-value>3</param-value>
</context-param>
<context-param>
<param-name>tapestry.thread-pool.max-pool-size</param-name>
<param-value>200</param-value>
</context-param>

When I use the following settings in web.xml I get 20 threads

<context-param>
<param-name>tapestry.thread-pool.core-pool-size </param-name>
<param-value>20</param-value>
</context-param>
<context-param>
<param-name>tapestry.thread-pool.max-pool-size</param-name>
<param-value>20</param-value>
</context-param>

I noticed that the documentation says the default max-pool-size is 20 ( http://tapestry.apache.org/parallel-execution.html ) while the API docs say the default is 10 ( http://tapestry.apache.org/current/apidocs/org/apache/tapestry5/ioc/IOCSymbols.html ).

I am invoking my threads from a service which contains

@Inject
private ParallelExecutor executor;

@Override
public void doStartThread() {
if ( myFuture == null || myFuture.isDone() ) {
myFuture = executor.invoke(new MyInvokable());

I have tried in Jetty 8.1.2 (Run Jetty Run in Eclipse) and Tomcat 7.0.52.

Cheers
