How to report bug in IBM java?

Does anybody know where I report bugs in the IBM java virtual machine?

IBM java reports invalid week of year for Icelandic location, because if incorrect first day of week and minimial days in first week.

When I run this code in SUN Java 1.4

Locale loc = new Locale(“is”,“IS”);

Calendar c = Calendar.getInstance(TimeZone.getDefault(),loc);

System.out.println(“java.version=”+System.getProperty(“java.version”));

System.out.println(“FirstDayOfWeek=”+c.getFirstDayOfWeek());

System.out.println(“MinimalDaysInFirstWeek=”+c.getMinimalDaysInFirstWeek());

System.out.println(“Country=”+loc.getDisplayCountry());

I get:

java.version=1.4.2_05

FirstDayOfWeek=2

MinimalDaysInFirstWeek=4

Country=Iceland

However running this in Lotus Notes 6.5.3 displays:

java.version=1.3.1

FirstDayOfWeek=1

MinimalDaysInFirstWeek=1

Country=Ísland

Which is incorrect.
