Andreas Christoforides commented on MTOMCAT-257:
------------------------------------------------
I am having a similar issue but with the Google Guava dependency (version
15.0).
Setup:
* useSeparateTomcatClassLoader is enabled
* Google Guava version in dependency management is 15.0
* Using tomcat6:run
I was getting a NoSuchMethodException when using a Google Guava method that was
added in version 15.0. I enabled the -verbose:class flag and I noticed that all
the Google Guava classes for my webapp were being loaded from version 10.0.1
instead of version 15.0.
The problem does NOT occur when running the WAR in a standalone Tomcat instance.
Google Guava version 10.0.1 is actually one of the dependencies of the Maven
Tomcat plugin itself. It seems that dependencies from the plugin are mixed with
the webapp even if the setting useSeparateTomcatClassLoader is enabled.
> Classpathes separation between plugin and application is broken (can't use
> slf4j-jcl in app)
