Subject [jira] Created: (HARMONY-721) kernel class VM lacks intern() method
Date Fri, 30 Jun 2006 14:43:29 GMT
kernel class VM lacks intern() method
-------------------------------------

         Key: HARMONY-721
         URL: http://issues.apache.org/jira/browse/HARMONY-721
     Project: Harmony
        Type: Bug

  Components: VM  
 Environment: Linux/ia32
    Reporter: Salikh Zakirov


The removal of String and StringBuffer classes (HARMONY-666) from DRLVM has missed the necessary
update
to org.apache.harmony.kernel.vm.VM.

The following test reproduces the problem:
---8<---
public class StringIntern {
    public static void main(String[] args) {
        String s = "abcde";
        String s0 = "abcde".intern();
        String s1 = ("abc" + "de").intern();
        String s2 = ("ab" + "cde").intern();
        if (s0 != s1 || s1 != s2) {
            System.out.println("FAIL: incorrect interning");
        } else if (s != s0) {
            System.out.println("FAIL: literal is not interned");
        } else {
            System.out.println("PASS");
        } 
    }    
}         
---------

Current output on Linux/ia32 is
$ ./lnx_ia32_gcc_debug/deploy/jre/bin/ij -cp ./lnx_ia32_gcc_release/semis/vm/_smoke.tests/classes
 util.StringIntern
java.lang.NoSuchMethodError: Can't find method org/apache/harmony/kernel/vm/VM.intern(Ljava/lang/String;)Ljava/lang/String;
while resolving constant pool entry at index 59 in class java/lang/String
        at util.StringIntern.main()
