JAVA Access denied - ES upgrade to 7.1

Hi all I have this issue when I try to run ES.

ERROR Could not register mbeans java.security.AccessControlException: access denied ("javax.management.MBeanT rustPermission" "register")

ERROR: [1] bootstrap checks failed
[1]: initial heap size [2147483648] not equal to maximum heap size [32178700288]; this can cause resize pauses and prevents mlockall from locking the entire heap.

Having some problem in fixing this issue.

Fixes I found online: Added : permission javax.management.MBeanTrustPermission "register"; to /etc/elasticsearch-master/jdk/conf/security/policy, but it does not help.

Do I need to add the links for the new ES in /var/lib/dpkg/info/elasticsearch.list?

Did you set security?

I think you need to have min and max heap size the same in jvm file.

This is the issue you need to deal with. Ther other problems are just noise that are very hard for us to hide.
