ServiceHelper.CacheClearoutListener.add(BundleContext, ServiceKey) causes
NPE if system bundle is hidden
Thomas Watson created ARIES-971:
-----------------------------------
Summary: ServiceHelper.CacheClearoutListener.add(BundleContext, ServiceKey) causes NPE if system bundle is hidden
Key: ARIES-971
URL: https://issues.apache.org/jira/browse/ARIES-971
Project: Aries
Issue Type: Bug
Components: JNDI
Environment: All
Reporter: Thomas Watson
In org.apache.aries.jndi.services.ServiceHelper.CacheClearoutListener.add(BundleContext, ServiceKey) the following code will cause an NPE:
// try to use the system bundle for our listener,
// if that fails we fall back to the calling context
BundleContext systemBundle =
AccessController.doPrivileged(new PrivilegedAction<BundleContext>() {
public BundleContext run()
{
return ctx.getBundle(0).getBundleContext(); <<< NPE here
}
});
This can happen if a bundle FindHook hides the bundle 0 from the ctx bundle. A check for null should be done here:
BundleContext systemBundle =
AccessController.doPrivileged(new PrivilegedAction<BundleContext>() {
public BundleContext run()
{
Bundle system = ctx.getBundle(0);
return system == null ? null : system.getBundleContext();
}
});
This would allow jndi to work in such environments where bundle, service, and resolver hooks are used for isolation (e.g. subsystems).
