When setting log level to trace, NullPointer occurs in RootInterceptor
----------------------------------------------------------------------
Key: JBSEAM-438
URL: http://jira.jboss.com/jira/browse/JBSEAM-438
Project: JBoss Seam
Issue Type: Bug
Affects Versions: 1.1.0.CR1
Reporter: Guy Veraghtert
When setting log level to trace, NPE occurs in method invokeInContexts of RootInterceptor class.
According to the EJB 3 spec, p. 308, method getMethod of class InvocationContext returns null for lifecycle callbacks.
The invokeInContexts method is invoked in the PostConstruct, resulting in a NPE:
log.trace("intercepted: " + getComponent().getName() + '.' + invocation.getMethod().getName());
Locally patched this way:
private Object invokeInContexts(InvocationContext invocation, EventType eventType) throws Exception
{
if ( isProcessInterceptors() )
{
if ( log.isTraceEnabled() )
{
//FIXME Fixed problem with the invocationContext in @AfterConstruct getMethod() returns null! (see spec p. 308)
log.trace("intercepted: " + getComponent().getName() + '.' + ((invocation.getMethod() !=null) ? invocation.getMethod().getName() : "POSTCONSTRUCT"));
}
return new SeamInvocationContext( invocation, eventType, userInterceptors, getComponent().getInterceptors(type) ).proceed();
}
else {
if ( log.isTraceEnabled() )
{
log.trace("not intercepted: " + getComponent().getName() + '.' + invocation.getMethod().getName());
}
return invocation.proceed();
}
}
