Subject [jira] Updated: (HARMONY-1751) Classlib test org.apache.harmony.prefs.tests.java.util.prefs.PreferencesTest.testSystemNodeForPackage() fails

Stepan Mishura updated HARMONY-1751:
------------------------------------

    Attachment: fixFor_getNode.patch

Hi

Ilya, thanks for your comments on native code - you are right that getNode() algorithm is
correct. However I still think that the bug in native code and the following line is incorrect:
err = openRegKey (env, jpath, jUserNode, &hKey, KEY_QUERY_VALUE);

I assume that Elena didn't have KEY_QUERY_VALUE permission on test machine. Please review
and try a patch (fixFor_getNode.patch) to fix the issue with Preferences.systemNodeForPackage(Object.class);
 

Steps to verify the fix (should work on Harmony and RI):
1) Apply the patch and do 'ant build-native'
2) create test that only invokes: Preferences.systemNodeForPackage(Object.class);  
3) deny all permission for HKEY_LOCAL_MACHINE / SOFTWARE / JavaSoft / Prefs
4) run the test - it MUST fail with SecurityException
5) allow 'Create Subkey' permission only for HKEY_LOCAL_MACHINE / SOFTWARE / JavaSoft / Prefs
6) run the test - it MUST pass
7) allow all permissions only for HKEY_LOCAL_MACHINE / SOFTWARE / JavaSoft / Prefs
8) press refresh (F5) on 'Prefs' entry - java/lang sub-entries MUST exist

Thanks,
Stepan.
