Subject: Improved fix for 45528 (invalid SSL config).
X-Git-Url: https://git.internetallee.de/?a=commitdiff_plain;h=7a91561bbad55515357443096191134e8e58632d;p=tomcat7.0

Improved fix for 45528 (invalid SSL config).
It is a variation on the previous patch that:
- does the check earlier
- uses an unbound socket so there is no possibility of a client connection
- uses the String manager for the error message
Note: I gave up on the alterntaive javax.crypto.Cipher suggestion as the cipher names are different and there is no easy conversion.
