Java Error when launching application.

Error:

java failed to validate certificate application will not be executed

Resolution:

Open File: 
(Windows)
C:Program Files (x86)Javajre7libsecurityjava.security
(Linux)
/usr/java/jre1.7.0_45/lib/security/java.security

(This file location is obviously based on the version and install you have).
If in doubt you are looking for "java.security"

Comment Out:
jdk.certpath.disabledAlgorithms=MD2, RSA keySize < 1024
Or if it exists:
jdk.certpath.disabledAlgorithms=MD2, RSA keySize < 2048

Save the file.
Restart Java Application

When saving file you may have to open the file as administrator in order to save it.
