Why do i get javax.net.ssl.SSLHandshakeException when attempting a product install

When attempting to install the EC product One sometimes gets the error message :

The Eclipse PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

To resolve this issue modify the eclipse.ini file in order to use the Microsoft Certificate Trust Store, in which the missing certificate is included:

Add the following lines into the "eclipse.ini" file right after the line:"-vmargs"

-Djavax.net.ssl.trustStore=NUL

-Djavax.net.ssl.trustStoreType=Windows-ROOT
