Scott Mitchell 4be25ca599 Workaround IBM's J9 JVM getSupportedCipherSuites() returning SSL_ prefix cipher names 
Motivation:
IBM's J9 JVM utilizes a custom cipher naming scheme with SSL_ prefix [1] instead of the TLS_ prefix defined by TLS RFCs and the JSSE cihper suite names [2]. IBM's documentation says that the SSL_ prefix are "interchangeable" with cipher names with the TLS_ prefix [1]. To work around this issue we parse the supported cipher list and see an SSL_ prefix we can also add the same cipher with the TLS_ prefix. For more details see a discussion on IBM's forums [3] and IBM's issue tracker [4].

Modifications:
- When parsing the supported cipher list to get the supported ciphers and we encounter a SSL_ prefix we should also add a TLS_ prefix cipher.
- Remove SSL_ prefix ciphers from Http2SecurityUtil.

Result:
Work around for IBM JVM's custom naming scheme covers more cases for supported cipher suites.

How to build

For the detailed information about building and developing Netty, please visit the developer guide. This page only gives very basic information.

You require the following to build Netty:

Note that this is build-time requirement. JDK 5 (for 3.x) or 6 (for 4.0+) is enough to run your Netty-based application.

Branches to look

Development of all versions takes place in each branch whose name is identical to <majorVersion>.<minorVersion>. For example, the development of 3.9 and 4.0 resides in the branch '3.9' and the branch '4.0' respectively.
