Willem Jiang commented on CAMEL-12610:
--------------------------------------
Just found the current camel bean cached option is false by default , but it
doesn't make sense that we keep the converted processor by default in
AbstractBeanProcessor. Can we set the default camel bean cached option to be
true?
> Camel bean component invokes cached instance of bean (that impl processor) in
> Registry

> Environment: N/A
> Reporter: Jan Bednar
> Assignee: Willem Jiang
> Priority: Minor
> Fix For: 2.21.2, 2.22.1, 2.23.0

> Every invocation of bean component should query Registry for actual instance.
> Now it is cached in {{BeanProcessor#delegate}} variable, even if endpoint
> parameter {{cache=false}} specified.
> This behavior breaks java-ee compliance:

> {quote}Every invocation of the [{{Context.get(Contextual,
> CreationalContext)}}|https://docs.oracle.com/javaee/7/api/javax/enterprise/context/spi/Context.html#get-javax.enterprise.context.spi.Contextual-javax.enterprise.context.spi.CreationalContext-]
> operation of the context object for the {{@Dependent}} scope returns a new
> instance of the given bean.

> Marking this as Major, because upgrading of Camel from 2.19.x to 2.2x.x leads
> to unpredictable results in CDI environment. Since this is tied to CDI
> environment, this issue is hard to notice even in well junit covered
> application and can result in major issues in pre-production or production
> environment.
> Full reproducible project with unit test and deployable WAR package, which
> passes with 2.19.x and lower. Fails with 2.20.x and higher [on
> Github|https://github.com/bedlaj/camel-dependent-bean].
> Attachments are based on version 2.21.1
