Aled Sage created WELD-1074:
-------------------------------
Summary: Using `new Weld()` fails with
java.lang.IncompatibleClassChangeError when Guava on classpath?
Key: WELD-1074
URL: https://issues.jboss.org/browse/WELD-1074
Project: Weld
Issue Type: Bug
Components: Bootstrap and Metamodel API
Reporter: Aled Sage
I am running Weld in a vanilla JVM using `new Weld()` (having been blocked in
AS 7 by https://community.jboss.org/thread/154405).
I am getting the error shown below. I presume Weld is doing some special
classloading that causes it to pick up Guava from somewhere other than the head
of the classpath? My question/bug is:
* is the classloading behaviour documented; are there things that a user must
not do?
* is this error caused by me having Guava ahead of the weld jar on the
classpath, and if so can such errors be avoided in weld? Or is it just always
necessary to avoid having Weld dependencies ahead of
---
I have built Weld myself from master (1.1.6-SNAPSHOT, git commit 282f830) so
have the version with guava dependency 11.0.2.
(Thanks Ales for fixing that one!)

(note I also put in an extra catch block into BeanDeployer so that it would
tell me which class it was trying to load when it got this error).
