[nio_char][drlvm] Strange effect on DRLVM with charsets

[Mikhail Markov]

Hi!

While investigating H-3307 I've found a strange effect on DRLVM. The
following code:
import java.nio.charset.Charset;

public class Test {
   public static void main(String[] args) {
       System.out.println("print something...");
       Charset charset = Charset.forName("ISO-8859-1");
       charset.encode("\u3400");
       System.out.println("print something again...");
       System.out.println("and again...");
   }
}

prints additional symbols after charset.encode() line at the end of messages
in println():
print something...
print something again...→
and again...→

If i remove charset.encode() line then the output is ok:
print something...
print something again...
and again...

Another strange thing that if i remove first println line in the code above,
the last 2 println works ok, i.e. without any additional symbols

This effect is only reproducible on DRLVM. I'm not quite understand what
happens here.

Any thoughts?

Thanks,
Mikhail
