Subject [jira] [Commented] (LANG-744) StringUtils throws java.security.AccessControlException on Google App Engine
Date Thu, 01 Sep 2011 10:02:09 GMT

    [ https://issues.apache.org/jira/browse/LANG-744?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13095211#comment-13095211

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

The message will be thrown even if the sun method is not needed; that does not seem right.

If the sun method is unavailable, the code that conditionally calls it throws UnsupportedOperationException:

"The stripAccents(CharSequence) method requires at least Java 1.6 or a Sun JVM");

We could record the Exception in the static block, and add it as the cause for the UOE.
It would then only appear when necessary.

> 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)

> The exception should be caught in the catch clauses around loadClass("sun.text.Normalizer").
> Commons lang 2 worked fine on GAE.
