Java and JavaScript in the Database

Hello,

I have a Java stored procedure that has been working well in earlier Oracle Database releases but it doesn't work in Oracle Database 12.2.0.1 (Windows platform).

I've pinpointed the problem into this line:

DatagramSocket ds = new DatagramSocket();

This line causes the following error:

ORA-29516: Aurora assertion failure: Assertion failure at eoxdebug.c:105

jondsp_init_i_ds is not yet implemented

Any ideas how to avoid this? How come it is working on earlier releases but "not yet implemented" now?

Thanks!
