NPE in JandexFileSystemBeanArchiveHandler using Weld 2.2.14 on vmware tcserver

leo.mekenkamp Sep 15, 2015 10:41 AM

Hi all,

We have got an application that is running ok on a Tomcat 7 instance. When we try to deploy that application on a vmware tcserver instance, the application throws an exception:

15-Sep-2015 15:03:33.016 SEVERE [localhost-startStop-4] org.apache.catalina.core.ContainerBase.addChildInternal ContainerBase.addChild: start:

I connected a debugger and found out that on line 42 in JandexFileSystemBeanArchiveHandler, the super.handle(path) method is called with "WEB-INF/classes" as argument. The FileSystemBeanArchiveHandler, being the superclass of JandexFileSystemBeanArchiveHandler, returns a null. This causes an NPE.

My question: is there a way to disable Jandex handling in Weld, or is there another way to work around this bug?

I found a reference to a similar question on stackoverflow.com, but that question has been deleted, unfortunately. This bug seems quite rare.

cheers,

Hi Leo,
this NPE was fixed in 2.3 and master branch. You should move to 2.3.0.Final - we plan the release later this week. I will also add the fix to Weld 2.2.16.SP1 which also scheduled for the end of the week.

My question: is there a way to disable Jandex handling in Weld, or is there another way to work around this bug?

Yes, remove Jandex from the class path.

Ah, looking forward to that release then. Unfortunately removing Jandex from the class path leads to a ClassNotFoundException, so that is not an option. Thanks for your response.

Ehhm, well, the NPE I got earlier has been resolved in 2.2.16.SP1 Unfortunately a new one raised its ugly head:

Yep, you're right. I've created WELD-2038. Unfortunately, I'm not aware of any workaround (for your environment).

Thanks. Anything that I can do? Any idea on the timeframe for this bug? Don't mean to nag, but this bug is blocking for us, so I would like to know if I should be planning for alternative solutions.

Ok so I reproduced the above stack trace/problem with Weld 2.3.0.Final on Tomcat 8.0.26 where the deployment archive is not exploded. I also verified the fix, but let me think about some test as well...

I do not mean to be rude, but is there an indication on when this bug will be fixed? Is there something I can do to speed up that process? There is quite some pressure on my shoulders here, so I would like to know if I should be planning for a different route.

The relase dates for 2.2.17.Final and 2.3.1.Final are not scheduled yet. I believe both versions should be delivered during October 2015.

Good news. I build a nightly from a cloned git repo and tested the resulting 2.2.17-SNAPSHOT weld-servlet in our application: no more NPE's.

So a 'thank you' is in order: thank you.

Looking forward to the next official release.

For the record: we replaced the 2.2 version with the newly built 2.3.1.Final, and it works like a charm.
