BUFR reads file information incorrectly. Is there a problem with the design?

[zfy68]

code address : MessageCompressedDataReader.java

As shown in the figure below:
When I read BUFR compressed data, the data is encapsulated in an array. The data type is set during initialization. For example, the array type is byte, but this method sets the long type, which causes problems with the displayed value and is easily misleading.
