JDK 7 Certpathbuilder.build throws SunCertPathBuilderException when JDK 6 works

1. Attached 3-7885427021-testcase.tar.gz
2. cd testcase1-ng/
3. ./test.sh <jdk_home>

The testcase2-ok is similar code, the only change is
the empty intermediate keystore.

Tested with 6u51 - works.
7 FCS fails. 7u40 fails. 1.8.0-ea-b109 fails.


Running the same piece of code/certs/keystore with JDK 6 works.
JDK 7 fails with the following exception.

sun.security.provider.certpath.SunCertPathBuilderException: unable to find
valid certification path to requested target
