Hello.
Could you please review the proposed fix issue which is NOT applicable
for JDK 9:
BUGURL: https://bugs.openjdk.java.net/browse/JDK-8154009
WEBREV: http://cr.openjdk.java.net/~akosarev/8154009/webrev.00/
PROBLEM:
**/AddProvider/, /RemoveProvider///& /GetProviders///methods
of*//**/java.security.Security/* class results in calling
/doLoadProvider /method of *ProviderConfig *class for each Security
Provider.
And in this method we have a problem that it catches and processes
*Exception*, but doesn't process *ExceptionInInitializerError *which is
thrown in case of missing permissions:
permission java.lang.RuntimePermission "loadLibrary.*";
permission java.io.FilePermission "<<ALL FILES>>", "read";
permission java.lang.RuntimePermission
"accessClassInPackage.sun.security.*";
Those permissions are unavailable if we switch-off
*jre/lib/security/java.policy* file by running program with option:
/-Djava.security.policy==<policy_file>/
FIX:
In JDK9 *ProviderConfig *class is changed in the scope of
JDK-8043406 <https://bugs.openjdk.java.net/browse/JDK-8043406>
enhancement (that is why JDK-8154009 is not applicable for JDK 9).
And in order to fix above problem in JDK 8 we just require to take
same changes for *ProviderConfig *class in JDK 9:
See changeset from JDK 9:
http://hg.openjdk.java.net/jdk9/dev/jdk/diff/7f8294841146/src/share/classes/sun/security/jca/ProviderConfig.java
REGRESSION TESTS:
2 existing tests (*AddProvider*, *RemoveStaticProvider*) were used
and modified so that they provide testing for fixed situation
(additional permissions are not required any longer for /AddProvider
/&**/RemoveProvider /methods.)
1 new test was written for checking /GetProviders /method under
restricted permissions.
Changes were successfully tested by JPRT.
Best regards,
Artem Kosarev.
