---------------------------------
Assignee: Karl Pauls
> issue with SecurityManagerEx
> ----------------------------
>
> Key: FELIX-5914
> URL: https://issues.apache.org/jira/browse/FELIX-5914
> Project: Felix
> Issue Type: Bug
> Components: Framework
> Affects Versions: framework-6.0.1
> Reporter: Tom Rutchik
> Assignee: Karl Pauls
> Priority: Major
> Fix For: framework-6.0.2
>
> Original Estimate: 0.5h
> Remaining Estimate: 0.5h
>
> The class SecurityManagerEx is a wrapper class around
> java.lang.SecurityManager so that it can expose access to the protected
> method getClassContext which returns a Class[].
> The code as it currently is coded looks like this:
> {color:#000080}public {color}Class[] getClassContext()
> {return {color:#000080}super{color}.getClassContext(); }
> It looks fine, however, super.getClassContext() at least in the Android
> implementation returns null. Here's the Android's implementation code for
> java.lanaguage.SecurityManager:
> {color:#000080}public {color}Object getSecurityContext() {
> {color:#000080}return null{color};
> }
> SecurityManager.getClassContent() is called in the class BundleWiringImpl in
> the method
> {color:#000080}private {color}Object
> tryImplicitBootDelegation({color:#000080}final {color}String name,
> {color:#000080}final boolean {color}isClass)
> it passes the result of {color:#333333}SecurityManager.getClassContent()
> (which is null - parameter name classes) to the method
> doImplicitBootDelegation. Here's what that code looks like:{color}
> {color:#000080}private {color}Object doImplicitBootDelegation(Class[]
> classes, String name, {color:#000080}boolean {color}isClass)
> {color:#000080}throws {color}ClassNotFoundException,
> ResourceNotFoundException
> {
> {color:#808080}// Start from 1 to skip security manager class.
> {color} {color:#000080}for {color}({color:#000080}int {color}i =
> {color:#0000ff}1{color}; i < classes.{color:#660e7a}length{color}; i++)
> Since classes is null, classes.length throws an exception. This problem has
> in my case caused a bundleActivator not to be found.
> The best solution to the problem is to modify the
> SecurityManagerEx.getClassContext routine to the following:
> {color:#000080}public {color}Class[] getClassContext()
> {
> Class[] classes = {color:#000080}super{color}.getClassContext();
> {color:#000080}if {color}(classes == {color:#000080}null{color}) classes =
> {color:#000080}new {color}Class[{color:#0000ff}0{color}];
> {color:#000080}return {color}classes;
> }
