[teiid-issues] [JBoss JIRA] (TEIID-2952) Crypto exception with client/server running on different java versions

Crypto exception with client/server running on different java versions ---------------------------------------------------------------------- Key: TEIID-2952 URL: https://issues.jboss.org/browse/TEIID-2952 Project: Teiid Issue Type: Feature Request Components: JDBC Driver, Server Affects Versions: 7.7 Reporter: Steven Hawkins Assignee: Steven Hawkins Priority: Critical Fix For: 8.7.1, 8.8 The DiffieHellman key generation logic varies by platform with the handling of leading 0's in the secret. 1.6 seems to strip while most 1.7 vms do not. A related Java bug is http://bugs.java.com/bugdatabase/view_bug.do?bug_id=8014618 which indicates Sun/OpenJDK JRE 7u17 - 8b94 are affected. If there is conflicting handling between the client/server then approximately 1 out of 256 connection attempts will fail with a bad padding exception, since the client/server will be operating against different symmetric keys.
