> Upgrade Felix framework to recent stable
> ----------------------------------------
>
> Key: AMDATU-382
> URL: http://jira.amdatu.org/jira/browse/AMDATU-382
> Project: Amdatu
> Issue Type: Improvement
> Components: Amdatu Core
> Reporter: Ivo Ladage - van Doorn
> Assignee: Bram de Kruijff
> Fix For: 0.3.0
>
> Attachments: felix302_deadlock_stackdump.txt

> Currently we run the Felix framework version 3.0.2. The latest version is
> 3.2.1.
> In the core integration test, the 3.2.1 version of the felix framework is
> used instead. Using this newer version I encountered an issue in the
> integration test, that will also occur in the Amdatu runtime. The problem
> manifests itself by the fact that the JSP bundle doesn't start, caused by
> this error:
> {noformat}
> JAXP: find factoryId =javax.xml.parsers.DocumentBuilderFactory
> JAXP: found jar
> resource=META-INF/services/javax.xml.parsers.DocumentBuilderFactory using
> ClassLoader: null
> JAXP: found in resource,
> value=org.apache.xerces.jaxp.DocumentBuilderFactoryImpl

> After debugging 3.0.2 and 3.1.2 it appeared to be caused by a change in the
> implicit boot delegation mechanism. See line 1446 (method
> doImplicitBootDelegation) in 3.0.2 and line 1521 (method
> doImplicitBootDelegation) in 3.2.1. In 3.0.2 the class is loaded from the
> parent classloader (which is the system classloader), in 3.2.1 this method
> returns null
