Subject [jira] [Commented] (DERBY-5611) Permissions granted by server.policy to derbytools.jar are not sufficient to run ij

Kathey Marsden commented on DERBY-5611:
---------------------------------------

I agree the tools permissions are there for the benefit of NetworkServerControl sysinfo.
Should this be closed Not a Problem?

> server.policy grants derbytools.jar the permission to read several system properties.
 However, at startup ij tries to read all of the system properties. This happens in ij.jj
in the initFromEnvironment() method. To call System.getProperties(), you need the following
permission:
>   permission java.util.PropertyPermission "*", "read,write";
> ij startup fails with this error trace:
> Exception in thread "main" java.security.AccessControlException: access denied (java.util.PropertyPermission
* read,write)
> 	at java.security.AccessControlContext.checkPermission(AccessControlContext.java:374)
> 	at java.security.AccessController.checkPermission(AccessController.java:546)
> 	at java.lang.SecurityManager.checkPermission(SecurityManager.java:532)
> 	at java.lang.SecurityManager.checkPropertiesAccess(SecurityManager.java:1252)
> 	at java.lang.System.getProperties(System.java:581)
> 	at org.apache.derby.impl.tools.ij.ij$1.run(ij.java:113)
> 	at java.security.AccessController.doPrivileged(Native Method)
> 	at org.apache.derby.impl.tools.ij.ij.initFromEnvironment(ij.java:111)
> 	at org.apache.derby.impl.tools.ij.utilMain.initFromEnvironment(utilMain.java:175)

> 	at org.apache.derby.impl.tools.ij.Main.main(Main.java:75)
> 	at org.apache.derby.tools.ij.main(ij.java:59)
> Here are some ways to fix this problem:
> 1) Remove the whole block of permissions for derbytools.jar. Maybe those permissions
don't belong in server.policy. Note that a similar block of permissions also appears in template.policy
with a comment suggesting that they are sufficient for running the Derby tools.
> 2) Add to the derbytools block the missing permission.
> 3) Re-write initFromEnvironment() so that it reads only a few properties rather than
all properties.
