Mamta A. Satoor commented on DERBY-6764:
----------------------------------------

Bryan, I have not seen "Plaintext connection attempt from an SSL enabled 
client?" during my testing for this jira. I have seen error "No appropriate 
protocol" when after removing the SSLv3 protocol, the only protocol left was 
TLS but NaiveTrustManager was looking for "SSL" in it's code SSLContext ctx = 
SSLContext.getInstance("SSL");. As part of my checkin for this jira, I changed 
NaiveTrustManager to look for TLS instead of SSL and that got rid of the "No 
appropriate protocol" error. 
Like you asked on DERBY-6771, I am wondering too if the user is indeed by 
accident trying to make a plaintext connection in case of SSL connection. I do 
not think he responded to that question. Looks like though he is going to try 
the latest 10.10 or 10.11 jars with SSLv3 protocol removed through the 
configuration file to see if the issue is with Derby 10.4

> Recently, a security weakness was found in SSLv3, POODLE: SSLv3 vulnerability 
> (CVE-2014-3566)
> Derby supports ssl between the client and network server.
> We should investigate this and decide if we need to change our product, e.g. 
> to eliminate support for SSL in favor of its successor TLS.
