[jboss-osgi-issues] [JBoss JIRA] Resolved: (JBOSGI-286) Investigate classloading of javax.* classes

Investigate classloading of javax.* classes ------------------------------------------- Key: JBOSGI-286 URL: https://jira.jboss.org/jira/browse/JBOSGI-286 Project: JBoss OSGi Issue Type: Bug Security Level: Public(Everyone can see) Components: Core Framework Reporter: Thomas Diesler Assignee: Thomas Diesler Fix For: Framework 1.0.0 Alpha3 The Framework must always delegate any package that starts with java. to the parent class loader. Certain Java virtual machines, also SUN's VMs, appear to make the erroneous assumption that the delegation to the parent class loader always occurs. This implicit assumption of strictly hierarchical class loader delegation can result in NoClassDefFoundErrors. This happens if the virtual machine implementation expects to find its own implementation classes from any arbitrary class loader, requiring that packages loaded from the boot class loader not be restricted to only the java.* packages. Other packages that must be loaded from the boot class loader can therefore be specified with the System property: org.osgi.framework.bootdelegation The packages in javax.* are NOT on the boot classpath by default
