[jira] Created: (HARMONY-1100) [classlib][io] compatibility:
Harmony method DataOutputStream(null).writeBytes("") throws NPE while RI
does not
[classlib][io] compatibility: Harmony method DataOutputStream(null).writeBytes("") throws NPE while RI does not
---------------------------------------------------------------------------------------------------------------
Key: HARMONY-1100
URL: http://issues.apache.org/jira/browse/HARMONY-1100
Project: Harmony
Issue Type: Bug
Components: Classlib
Reporter: Vladimir Ivanov
The spec says for the java.io package: "Unless otherwise noted, passing a null argument to a constructor or method in any class or interface in this package will cause a NullPointerException to be thrown".
and says nothing about 'null' for DataOutputStream constructor.
So, according to spec the DataOutputStream(null) should lead to the NPE instead of writeBytes but according to RI no NPE for constructor and zero-length string for writeBytes.
=================== test.java =========================
import java.io.DataOutputStream;
public class test {
public static void main(String args[]) throws Exception {
System.out.println("res = " + new DataOutputStream(null));
new DataOutputStream(null).writeBytes("");
System.out.println("OK");
}
}
===================================================
