Preemptive strike at The Hague?

This report notes that Pakistan has seemingly conducted a preemptive strike that could affect the case of Indian national Kulbhushan Jadhav by modifying its accession to the International Court of Justice's compulsory jurisdiction so as to exclude matters relating to national security. Here is Pakistan's communiqué to the UN (highlighting added):

29 March 2017

I have the honor, by direction of the President of the lslamic Republic of Pakistan to declare that [the] Government of the Islamic Republic of Pakistan recognizes as compulsory ipso facto and without special agreement in relation to any other State accepting the same obligation, the jurisdiction of the International Court of Justice under the Statute of the International Court of Justice.
