A recent issue from the JDK-8148516 fix can cause issue for some TLS servers. The problem originates from an *IllegalArgumentException* thrown by the TLS handshaker code.

```java.lang.IllegalArgumentException: System property jdk.tls.namedGroups(null) contains no supported elliptic curves```

The issue can arise when the server doesn't have elliptic curve cryptography support to handle an elliptic curve name extension field (if present). Users are advised to upgrade to this release. By default, JDK 7 Updates and later JDK families ship with the SunEC security provider which provides elliptic curve cryptography support. Those releases should not be impacted unless security providers are modified.
