Hi All,
I installed Sun 1.4.2 a while ago, and I am very happy with its
performance in Linux, However there is bug on this release that seems to
affect VisAD. The problem that araises in Visad is that some points in
a lines (e.g. Grid2Dset) are given the vaule "Infinity", which makes the
line go across the image

The exception I got is:

This is a known bug in Java. The report can be found in
http://developer.java.sun.com/developer/bugParade/bugs/4755500.html
It affected previous versions of Java, and it seems it affects as well
this new release.
Is it possible to come up with a workaround for this bug? Is it
actually the same bug.
REPRODUCIBILITY :
This bug can be reproduced always.
---------- BEGIN SOURCE ----------
public class MathBugTest {
public static void main(String[] args) {
System.out.println(Math.round(1d)); // prints "1", as expected
for (int i=0; i<2000; i++) {
Math.round(Double.NaN);
}
System.out.println(Math.round(1d)); // prints "0", which is wrong
}
}
---------- END SOURCE ---------
Thanks,
Ricardo
