连接mysql，java代码抛出：Invalid TLS padding data异常，是什么原因呢？

client抛出：

Caused by: javax.crypto.BadPaddingException: Invalid Padding length: 102
at sun.security.ssl.CipherBox.removePadding(CipherBox.java:746)
at sun.security.ssl.CipherBox.decrypt(CipherBox.java:491)
at sun.security.ssl.InputRecord.decrypt(InputRecord.java:172)
at sun.security.ssl.SSLSocketImpl.readRecord(SSLSocketImpl.java:1017)

而mysql的mysql.log日志里大量抛出如下异常：

[note] Got an error reading communication packets.
