Contributing a service to the Alias service configuration fails if the service
uses a non-standard scope, such as perthread
---------------------------------------------------------------------------------------------------------------------------
Key: TAPESTRY-1596
URL: https://issues.apache.org/jira/browse/TAPESTRY-1596
Project: Tapestry
Issue Type: Bug
Components: tapestry-core, tapestry-ioc
Affects Versions: 5.0.4
Environment: 5.0.5-SNAPSHOT
Reporter: Howard M. Lewis Ship
Assignee: Howard M. Lewis Ship
The issue is that the ServiceLifecycleSource service is making indirect use of
the Alias service for some of its dependencies. Thus the Alias service must be
fully instantiated for SLS to be instantiated, but when contributing a service
to Alias, the SLS must be instantiated first, to provide the necessary proxy.
Need to defer out the creation of the proxy.
Caused by: java.lang.RuntimeException: Error invoking service contribution
method
org.apache.tapestry.ioc.services.TapestryIOCModule.contributeServiceLifecycleSource(MappedConfiguration,
ObjectLocator): Error invoking constructor
org.apache.tapestry.ioc.internal.services.PerThreadServiceLifecycle(ThreadCleanupHub,
ClassFactory) (at PerThreadServiceLifecycle.java:54) (for service
'ServiceLifecycleSource'): Exception constructing service 'Alias': Construction
of service 'Alias' has failed due to recursion: the service depends on itself
in some way. Please check
org.apache.tapestry.services.TapestryModule.build(Log, String, AliasManager,
Collection) (at TapestryModule.java:248) for references to another service that
is itself dependent on service 'Alias'.

public PerThreadServiceLifecycle(ThreadCleanupHub threadCleanupHub,

ClassFactory classFactory)
{
_threadCleanupHub = threadCleanupHub;
_classFactory = classFactory;
}
A temporary fix would be for the ThreadCleanupHub to be injected using
@InjectService.
