[~aboukhal] thanks for confirmation. Yes, after setting kie.security.policy I can reproduce the problem. I need to debug that to check if your fix is the correct one. Not sure when this will happen, because of holidays, but I will definitely take a look at the beginning of next year, right after holidays. I will keep you updated in the PR or here.

Hi [~tzimanyi],
thanks for your test case. It is perfect in demonstrating the bug. It seems you just forgot to set the property {{-Dkie.security.policy="replace_me_with_path_to_policy_file_for_rules"}}. If you run the test with that property (you can even point it to the same permissive policy that you used for the whole JVM) you should see the exception.

[JBoss JIRA] (DROOLS-3429) Serialization of KiePackages fails when SecurityManager is enabled
by Tibor Zimányi (Jira)
[ https://issues.jboss.org/browse/DROOLS-3429?page=com.atlassian.jira.plugi... ]
Tibor Zimányi commented on DROOLS-3429:
---------------------------------------
Hi [~aboukhal], I cannot reproduce the problem based on your descripton. I created a test class [1], then I added AllPermission permission to my java.policy file, added "-Djava.security.manager" flag to the test run and it works. As you can see from the test class I also tried to add the policy programatically, with same results. Could you please check the test if it matches your case? If not, could you please provide a reproducer? Maybe my test class might help you with developing one. I ran the test using master branch and 7.14.x branch both with Oracle JDK 8 and IBM JDK 8.
