Thanks for the solution, Claus!

> Key: CAMEL-8500
> URL: https://issues.apache.org/jira/browse/CAMEL-8500
> Project: Camel
> Issue Type: Bug
> Components: camel-core
> Affects Versions: 2.13.4
> Environment: Apache Camel 2.13.4 running on JBoss EAP4
> Reporter: Carsten Erker
> Assignee: Claus Ibsen
> Fix For: 2.14.3, 2.15.1, 2.16.0

> *Problem*
> When starting the DefaultCamelContext, Camel tries to get a
> PropertiesComponent object from JNDI under the name "properties" (which is
> hard-coded in DefaultCamelContext.lookupPropertiesComponent() resp.
> CamelContextHelper.lookupPropertiesComponent() in newer Camel versions).
> During start we get the following Error:
> {code}
> org.apache.camel.NoSuchBeanException: Found bean: properties in JNDI Context:
> javax.naming.InitialContext@a37a18 of type: org.jnp.interfaces.NamingContext
> expected type was: class

> ... 145 more
> {code}
> *Reason*
> In our installation, some properties are bound to the name "properties/..."
> in the JNDI global namespace.
> *Proposed Solution*
> Camel can manage if it finds nothing under the JNDI name, the problem is just
> finding something different than the expected PropertiesComponent instance.
> Instead of calling JndiRegistry.lookupByNameAndType(String, Class) -- this is
> where the cast fails -- we should call JndiRegistry.lookupByName(String
> name). If an instance other than a PropertiesComponent is returned here, we
> should go on as if nothing was found in the JNDI lookup.
> I can provide a pull request for this.
