[drlvm][jit] Jitrino/OPT does not throw IncompatibaleClassChangeError when objectref in invokeinterface instruction refers to the class which does not implement used interface
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Key: HARMONY-2095
URL: http://issues.apache.org/jira/browse/HARMONY-2095
Project: Harmony
Issue Type: Bug
Components: DRLVM
Environment: Windows and Linux
Reporter: Vera Petrashkova
Attachments: intfTest.zip
If objectref in invokeinterface instruction refers to the class which does not implement used interface Jitrino/OPT does not throw IncompatibaleClassChangeError.
To reproduce this bug run the following intfTest. It invokes class intf_cl_2 which was created from jasmin code:
------------------intfTest.java------------------
import java.io.*;
public class intfTest {
public static void main (String[] args) {
try {
System.out.println("Test failed: " + new intf_cl_2().test());
} catch (IncompatibleClassChangeError e) {
System.out.println("Test passed: " + e);
e.printStackTrace();
} catch (Throwable e) {
System.out.println("Test failed: unexpected error");
e.printStackTrace();
}
}
}
-----------------------------------------------
public interface intf_1 {
public abstract int intfMethod();
}
-----------------------------------------------
public interface intf_2 {
public abstract int intfMethod();
}
----------------------------------------------
public class intf_cl_1 implements intf_1 {
public int intfMethod() {
return 105;
}
}
---------------------------------------------
.class public intf_cl_2
.super java/lang/Object
;
; standard initializer
.method public <init>()V
aload_0
invokespecial java/lang/Object/<init>()V
return
.end method
;
; test method
.method public test()I
.limit locals 2
.limit stack 2
new intf_cl_1
dup
invokespecial intf_cl_1/<init>()V
invokeinterface intf_2/intfMethod()I 1
bipush 105
ireturn
.end method
---------------------------------------------------
Create intf_cl_2 class using jasmin.jar
java -cp jasmin.jar intf_cl_2.jj
or use class file from attachment
And run test:
java -cp . -Xem:opt intfTest
