Subject [jira] [Commented] (LANG-744) StringUtils throws java.security.AccessControlException on Google App Engine
Date Mon, 12 Sep 2011 14:01:12 GMT

    [ https://issues.apache.org/jira/browse/LANG-744?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13102665#comment-13102665

Sebb commented on LANG-744:
---------------------------

It might be worth changing the static init to a lazy init (IOD).
This would reduce the overhead for applications that don't call stripAccents.

Even if it is possible to change permissions without reloading the class, I'm not sure we
check the methods each time.

> In the static initializer of org.apache.commons.lang3.StringUtils, there is an attempt
to load the class sun.text.Normalizer.
> Such a class is prohibited on Google App Engine, and the static intializer throws a java.security.AccessControlException.
> {code}
> Caused by: java.security.AccessControlException: access denied (java.lang.RuntimePermission
accessClassInPackage.sun.text)
> 	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.Class.getMethod(Class.java:1602)
> 	at org.apache.commons.lang3.StringUtils.<clinit>(StringUtils.java:739)
> {code}
> The exception should be caught in the catch clauses around loadClass("sun.text.Normalizer").
> Commons lang 2 worked fine on GAE.
