provider from the ibmjceplus.jar file.
ERROR DESCRIPTION:
***Three different customers have reported this same issue***
The below exception occurs when the application starts
exchanging data over SSL with IBMJCEPlus. This started
occurring after upgrading to Java 8.0.6.10. This problem is not
present if IBMJCE is used:

Problem conclusion

  • The problem was caused because the output buffer was the same
size as the input buffer. Since, the tag is added to the output
buffer the output  buffer needs to be larger by the tag length.
