> test/jdk/javax/net/ssl/compatibility/JdkInfo is a helper class for the compatibility tests. It is verifying whether a protocol or cipher suite is supported/enabled by setting all the allowed values as a string, and then invoking String contains() to return whether a specific version is supported. This approach is problematic when, for instance, supportedProtocols is equal to 'TLSv1.3,TLSv1.2', then supportedProtocols.contains("TLSv1") will return true, given that 'TLSv1' is effectively a substring of 'TLSv1.3'.
