[jira] Commented: (MNG-1898) Plugin classpath broken from 2.0 to
2.0.1
[ http://jira.codehaus.org/browse/MNG-1898?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=150809#action_150809 ]
Benjamin Bentmann commented on MNG-1898:
----------------------------------------
bq. the problem appeared to be that the RealmDelegatingClassLoader included the system classpath, which would have conflicted with Xerces, as best I can guess.
Actually, the {{RealmDelegatingClassLoader}} wasn't really delegating. The call hierarchy looked like
{noformat}
client calls ClassLoader.loadClass(String)
ClassLoader.loadClass(String) calls this.loadClass(String, boolean)
ClassLoader.loadClass(String, boolean) calls parent.loadClass(String, boolean)
RealmDelegatingClassLoader.loadClass(String, boolean) calls parent.loadClass(String, boolean) UPS
{noformat}
{{RealmDelegatingClassLoader}} didn't override the overload {{loadClass(String, boolean)}} and as such never called into {{ClassRealm.loadClass()}} which would have provided the requested Xerces implementation from the plugin dependencies.

> I'm working on a kodo plugin in the codehaus mojo sandbox. Using 2.0, it works fine. In 2.1, it can't find xercesImpl, which is a transitive dependency of the plugin. Did something change to cause new behavior (aka a bug) related to this? Just eyeballing the info below, in 2.0, the instance of classloader was org.codehaus.classworlds.RealmClassLoader but in 2.0.1 it is org.codehaus.plexus.util.RealmDelegatingClassLoader
>
> I tried specifying xercesImpl as a direct dependency and that didn't work either so I'm not sure it's related to the transitivity.

> Output from 2.0.1: (2.0 follows further below)
