Stepan Mishura commented on HARMONY-2940:
-----------------------------------------

The following test reproduces this race condition with BouncyCastle provider - Harmony throws
NullPointerException and RI pass.(Please note it can be reproduced with any signed jar)

import java.io.IOException;
import java.security.Permission;
import java.security.Security;
import java.util.PropertyPermission;
import java.util.jar.JarFile;

public class test {

  public static void main(String[] args) throws Exception {

     // suggested workaround
     Security.getProviders();

     final JarFile f = new JarFile("bcprov.jar");

     System.setSecurityManager(new SecurityManager() {

       int i = 0;
       public void checkPermission(Permission perm) {

         // race conditions
         if (perm instanceof PropertyPermission) {
           i++;
           try {
             if (i == 2) { 
               f.getInputStream(
                 f.getEntry("org/bouncycastle/jce/provider/BouncyCastleProvider.class"));
             }
           } catch (IOException e) {
             e.printStackTrace();
           }
         }
       }
    });

    f.getInputStream(
      f.getEntry("org/bouncycastle/jce/provider/BouncyCastleProvider.class"));
  }
}

>             Project: Harmony
>          Issue Type: Bug
>          Components: Classlib
>            Reporter: Leo Li
>         Assigned To: Stepan Mishura
>            Priority: Critical
>
> Here is a testcase:
> public void test()
> {
>     Class cls = Class.forName("org.bouncycastle.jce.provider.BouncyCastleProvider");
> }
> Harmony fails.
> After digging into it, I found that it is related with bcprov.jar has a certificate signed
by the signature provided by itself.  I  tried to remove it signature and move it into the
boot directory and it works.
> So I recommend to put an unsigned bcprov.jar into the boot directory.
