Failed to install the OAM using the LCM during the post-configure steps，SSL error

So running a single node full stack installation with LCM. All goes fine till post-configure, where the script fails trying to connect to NodeManager. It gives

Some sources suggest that I should modify the java.security file. But it didn't work.

I made a change to java.security in java_home

# Comment this line
jdk.certpath.disabledAlgorithms=MD2, DSA, RSA keySize \< 2048

And for the record, I'm using the JDK distributed with LCM. I believe it's 7u80.
