[drlvm][jit] VM does not throw NoClassDefFoundError if class declares method as "throws  exception"
and there is no this exception class implementation (Jitrino OPT)
---------------------------------------------------------------------------------------------------------------------------------------------------------------------

                 Key: HARMONY-1857
                 URL: http://issues.apache.org/jira/browse/HARMONY-1857
             Project: Harmony
          Issue Type: Bug
          Components: DRLVM
         Environment: Linux IA-32, Windows IA-32
            Reporter: Irina Arkhipets


If some class declares method as "throws  exception" and there is no implementation of this
exception class then VM does not throw NoClassDefFoundError correctly  when it tries to create
the instance of this class.

This bug is reproducible with opt and server_static modes only.

This bug is not reproducible with interpreter, jet, client and server.

The following test example demonstrates the bug:

--------- test.java ---------
public class test {
    public static void main(String [] args) {
        try {
            new TestClass();
            System.out.println("FAILED");
        } catch (NoClassDefFoundError e) {
            System.out.println("PASSED");
        }
    }
}

class MyThrowable extends Throwable {}

class TestClass {
    public void run() throws MyThrowable {}

    public void tryMe() {
        try {
            run();
        } catch (MyThrowable e) {}
    }
}
-------------------------------

Please, do the following steps to reproduce the failure:
1. Compile test.java source using JDK1.5.0 javac
2. Remove MyThrowable.class file from the working directory
3. Run the test with "-Xem:opt" switch ("java -Xem:opt test")

Sample output is:
...
FAILED
