The following two tests fail on Windows 2003 ES and Windows XP Pro X64 systems with java version 1.4.2_11-ea-b01 [windows-amd64 bundle].

javasoft.sqe.tests.api.java.lang.StrictMath.pow_test
javasoft.sqe.tests.api.java.lang.StrictMath.atan2_test

When you run these tests with 32bit JDK they pass with no errors.
I also tested on Solaris_AMD with 64bit bundle and 64bit libraries - tests pass ok.

Output observed when running attached script lang_fail.sh with 64bit JDK and 64bit libraries-
