Hi all,
The following bug is triggered by the combination of Jikes 1.21 with the current version of Kaffe from CVS. It is not triggered by Jikes + sunjava or by sunjavac + Kaffe...
With jikes+Kaffe, the following code:
-----------------------------------------------------------------
public class Bug {
static interface I1 {
public String toString();
}
static interface I2 extends I1 {
}
static class CBug implements I2 {
}
public static void main(String[] argv) throws Exception {
I2 b = new CBug();
System.out.println(b);
System.out.println(b.toString().length());
System.out.println(b.toString());
}
}
-----------------------------------------------------------------gives me this output with a freshly compiled version of Kaffe from CVS:
----------------------------------------------------------------- [EMAIL PROTECTED]:/tmp$ jikes Bug.java; kaffe Bug [EMAIL PROTECTED] 137009132 java.lang.OutOfMemoryError at java.io.Writer.write (Writer.java:185) at java.io.OutputStreamWriter.write (OutputStreamWriter.java:196) at java.io.PrintWriter.write (PrintWriter.java:542) at java.io.PrintWriter.write (PrintWriter.java:568) at java.io.PrintWriter.print (PrintWriter.java:204) at java.io.PrintWriter.println (PrintWriter.java:453) at java.io.PrintStream.println (PrintStream.java:389) at Bug.main (Bug.java:16) -----------------------------------------------------------------
which is obviously wrong, since the returned string should be "[EMAIL PROTECTED]", which does not have length 137009132...
I first noticed this bug in a much more complex program, where I would get NullPointerExceptions when calling any method on the string returned by toString().
Not sure whether this should be seen as a bug in Kaffe or Jikes -- but since Kaffe aims to run programs that work on Sun's JDK, I guess this should be fixed. I don't understand Kaffe well enough to do it, though.
Cheers, - Benja
