> Key: CAMEL-9448
> URL: https://issues.apache.org/jira/browse/CAMEL-9448
> Project: Camel
> Issue Type: Bug
> Components: camel-core
> Affects Versions: 2.14.1
> Reporter: Andy Fedotov
> Assignee: Claus Ibsen
> Priority: Minor
> Fix For: 2.15.0
>
>
> DefaultCamelContext uses LRUSoftCache for endpoints cache. LRUSoftCache store
> values as SoftReference which can be reclaimed by GC.
> DefaultCamelContext.removeEndpoints() does not take into account this fact.
> This sometimes leads to java.lang.NullPointerException.
> We are still tied to 2.14.x Camel, because of our target environment is IBM
> enterprise product running under IBM WAS / IBM JDK 1.6. But seems like this
> affects all latest Camel releases. Here is an example of error stack trace I
> observe from time to time...
