May be your lower java version. Check below link to java version for db2 database.

I encountered the same problem with WildFly. I am not sure, but could it be that your Java EE container has a classloader which does not allow Java classes in sun.io.*?

Some answers on Stackoverflow indicate that the sun.jdk module has to be activated in the server configuration to allow usage of sun.* classes.
