After updating the Java version to 8update481, I couldn't use Java Client to link KH1516AI.

If I use WinClient to link, it's ok.  What's the reason? 

It's because the Java change its security setting in 8update481.  Please disable delete the words "TLS_RSA_*," in java.security, below is the process.

1. Go to the path C:\Program Files\Java\jre-1.8\lib\security

2. Copy the file "java.security" and put it to the desktop.

3. Change the file name of the java.security to java.security_old.  Here please change the file in the path C:\Program Files\Java\jre-1.8\lib\security

4. Go to desktop and open the java.security to delete the "TLS_RSA_*,".  You could search the keyword below to find out the location.

5. After changing, please save the file and copy it back to the security folder.  Below is the path.

C:\Program Files\Java\jre-1.8\lib\security
