Weblogic JMS exception - Codes Helper - Programming Question Answer

an ancient project of the company needs new functions recently. In order to develop Webservice, I upgraded the Weblogic of the old system to 10jdk1.6.
however, some of the old business of the system will involve data Synchronize to another system. The weblogic of that system is 8jdk1.4. There"s never been a problem before.

but in the new environment, I tested the old business and found that the data Synchronize could not be carried out. In the process of InitialContext (property), initialization based on the ip of another system would fail. The error message of the other party"s system is as follows:

< 2018-7-5 03:27:00 GMT > < Error > < RJVM > < BEA-000503 > < Incoming message header or abbreviation processing failed >
weblogic.rjvm.BubblingAbbrever$BadAbbreviationException: Bad abbreviation value: "256"-with nested exception: [java.lang.NullPointerException]

similar problems found on the Internet are said to be caused by the weblogic version. I have tried to replace the local weblogic.jar package with each other"s system, but it still cannot be solved. Please help me.
