Cipher suite not supported by Java 1.7

One of the external service which we use require one of the below (GCM) cipher suites along with TLSv1.2 or above. I was able to enable TLSv1.2 but the ciphers (listed below) are not supported by Java 1.7. I tried adding the current JCE7 policy as well. We cannot upgrade to Java 1.8 for the moment. Any support on how to deal with this issue?

ECDHE-ECDSA-AES128-GCM-SHA256
ECDHE-RSA-AES128-GCM-SHA256
ECDHE-ECDSA-AES256-GCM-SHA384
ECDHE-RSA-AES256-GCM-SHA384
DHE-RSA-AES128-GCM-SHA256
DHE-RSA-AES256-GCM-SHA384

You can try to use additional Security Providers to add the missing ciphers. BouncyCastle for example runs on Java 1.7 and comes with the ciphers you mentioned. There is a question with an answer concerning that here on StackOverflow, so you might try that out.

Priorities should be changed in order to get the migration to Java 8 (better Java 11) done as soon as possible. Java 7 is OOL (out of line) for quite some time now and Java 8 still is but won't be for much longer.
