Load data to MariaDB fails by Hibernate/JPA in JBoss

Hi, this may not be a problem of MariaDB, but I just wanted to know whehter I can get some insights of the OutOfMemoeryError problem in my web application. I am using Java Hibernate to access MariaDB and the Web server is JBoss. I configured the application to automatically load a data file to MaraiDB by Hibernate:

LOAD DATA LOCAL INFILE '/home/marlon/ubuntu/src/main/resources/Context.txt' INTO TABLE Term FIELDS TERMINATED BY '\t' LINES TERMINATED BY '\n' (id,term_id,source,context,URL,publish_time);

The plain text file is around 180MB, and I have been able to load it this way when the web application is started. But yesterday I suddenly received this memory error. I can load the data using the command at MariaDB terminal. The issue may be coming from Hibernate, JBoss or my application, but hope I can get some comments or insights here.

My Java heap size is set as 4GB which should be more than enough to handle this data. Please pay attention to this:
