Description

Harmony has problems with null pointer exception catch under server or opt mode for Java applications.

The following shows a test example:

public class Btest5710 {

Object obj;

public static void main(String [] args)

{ (new Btest5710()).test(); }

public void test() {
System.err.println("Start Btest5710 test...");
try

{ sync(); System.err.println("FAILED: NullPointerException was expected"); System.exit(-99); }

catch (NullPointerException e)

{ System.err.println("PASSED: " + e); }

catch (Throwable e)

{ System.err.println("Unexpected exception was thrown:"); e.printStackTrace(); System.err.println("FAILED"); System.exit(-99); }

}

void sync() {
synchronized (obj)

{ obj = new Object(); }

}

}

When running in server or opt mode, error will happen and the following is the error message.
