java task and permissions in 1.7.0
Hi,
This task has been working fine until I recently upgraded to 1.7.0:
<target name="usage" description="This usage help">
<java classname="org.apache.tools.ant.launch.Launcher">
<arg value="-projecthelp"/>
</java>
</target>
In 1.7.0, I get the "exitVM disallowed" error. So I changed it to:
<target name="usage" description="This usage help">
<java classname="org.apache.tools.ant.launch.Launcher">
<arg value="-projecthelp"/>
<permissions>
<grant class="java.lang.RuntimePermission" name="exitVM.*"/>
</permissions>
</java>
</target>
and got:
java.lang.SecurityException: Permission
(java.util.PropertyPermission ant.home read) was not granted.
So here goes my _first question_: I thought any explicitly
granted/revoked permissions were accumulative on top of the base set?
Then I tried granting AllPermission:
<target name="usage" description="This usage help">
<java classname="org.apache.tools.ant.launch.Launcher">
<arg value="-projecthelp"/>
<permissions>
<grant class="java.security.AllPermission"/>
</permissions>
</java>
</target>
and got the same error:
java.lang.SecurityException: Permission
(java.util.PropertyPermission ant.home read) was not granted.
So my _second question_ is quite obvious: why doesn't AllPermission
grant, well, all the permissions?
In the end I had to work around by adding fork="true" clonevm="true",
but it just looks silly to fork a vm in order to print out project help.
Thanks for any hint as to what I'm missing here.
