JDBC connector reads incorrect data from unix socket when the text is too large

I created the following table:

create table test_table

(

    int_column int        null,

    mediumtext_column     mediumtext null

)

    collate = utf8mb3_bin;

I stored 100 in the int_column and a large text (30000 chars) in the mediumtext_colum.
Then I read the data via Unix socket (jdbc:mariadb:///test-int?user=<user>>&password=<password>&localSocket=/tmp/mysql.sock).

Instead of reading the 100 for the int value I get -624824290 and the text length is 98 characters instead of 30000.

The error does not occur when using a TCP/IP database connection.

I attached my test case .
