Re: [Trinidad] java.lang.IllegalStateException: Factory already available for this class loader
Hi Matthias,
It happens on Windows as well.
After some investigation I found out that the trouble maker is method
org.apache.myfaces.trinidadinternal.config.GlobalConfiguratorImpl#init(javax.faces.context.ExternalContext),
and the critical section is
if (!_initialized)
{
try
{
_services =
ClassLoaderUtils.getServices(Configurator.class.getName());
// Create a new RequestContextFactory is needed
if (RequestContextFactory.getFactory() == null)
{
RequestContextFactory.setFactory(new RequestContextFactoryImpl());
}
// Create a new SkinFactory if needed.
if (SkinFactory.getFactory() == null)
{
SkinFactory.setFactory(new SkinFactoryImpl());
}
which , when two request are being sent simultaneously straight after ther
server has just started, (occasionally) throws the IllegalStateException,
FACTORY_ALREADY_AVAILABLE_FOR_CLASS_LOADER . Either in
RequestContextFactory.setFactory or SkinFactory.setFactory.
I don't have the overall picture of the whole Trinidad architecture, but
just from what I see in the method's code , it seems to me that the
initialization of the factories should be in a synchronized block, using
webapp classloader as a lock.
