JDK 7
7 b102Fixed

Here is a very simple code to reproduce it : 

========================
bash-3.00$ cat Test.java
import java.security.*;
import sun.security.pkcs11.SunPKCS11;

public class Test {

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

            Provider p = new SunPKCS11(args[0]);
            Security.insertProviderAt(p, 1);

   }

}

============= Run with B62 =================

bash-3.00$  /java/re/jdk/7.0/promoted/all/b62/binaries/solaris-sparc/bin/javac Test.java
bash-3.00$  /java/re/jdk/7.0/promoted/all/b62/binaries/solaris-sparc/bin/java -Djava.security.manager Test ecprovider.cfg.bak
Error: Main method not found in class Test, please define the main method as:
   public static void main(String[] args)
Exception in thread "main" java.lang.RuntimeException: Main method not found in Test
        at sun.launcher.LauncherHelper.signatureDiagnostic(LauncherHelper.java:214)
        at sun.launcher.LauncherHelper.checkAndLoadMain(LauncherHelper.java:202)

===============Run with b35======================

bash-3.00$ /java/re/jdk/7.0/promoted/all/b35/binaries/solaris-sparc/bin/javac Test.java
bash-3.00$ /java/re/jdk/7.0/promoted/all/b35/binaries/solaris-sparc/bin/java Test ecprovider.cfg.bak

Error: Could not find the main class Test.
Error: A JNI error has occurred, please check your installation and try again

================================
When running with b62 , and enable java.security.manager , it thrown "Main method not found" RuntimeException , this is not the correct exception. 
However , it looks like the behaviour of b35 is correct . this is a regression.

EVALUATION In sun.lanucher.LauncherHelper: static void signatureDiagnostic(PrintStream ostream, Class<?> clazz) { String classname = clazz.getName(); Method method = null; try { method = clazz.getMethod("main", String[].class); } catch (Exception e) { ostream.println(getLocalizedMessage("java.launcher.cls.error4", classname)); throw new RuntimeException("Main method not found in " + classname); } ... The SecurityException was thrown in the clazz.getMethod(*) but swallowed in the next line.
