This branch of esgf-getcert explores use MyProxyLogon of http://grid.ncsa.illinois.edu/myproxy/MyProxyLogon/ instead of MyProxy and implements a own implementation to convert private key PKCS#8 in PKCS#1. So it can avoid the bug with openJDK versions (#2).
Also, this new implementation allows generate a getcert.jar smaller than MyProxy version getcert.jar.
new getcert.jar with MyProxyLogon -> 229,7 kB
old getcert.jar with MyProxy -> 2,5 MB
This new version has been run succesfully in openJDK 6/7 and JDK7.
