Subject [jira] Updated: (HARMONY-6499) [classlib][luni] URLStreamHandler.parseURL throws different exception to RI in some cases
Date Thu, 22 Apr 2010 09:51:49 GMT

     [ https://issues.apache.org/jira/browse/HARMONY-6499?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Catherine Hope updated HARMONY-6499:
------------------------------------

    Attachment: 6499-2.patch

Found another corner case for the parseURL method (when end index is less than 0 don't perform
bounds checks), so use this patch instead of the earlier one.

> java.net.URLStreamHandler throws a SecurityException in some situations where the RI
will throw a StringIndexOutOfBoundsException.  From experimenting with test cases I think
the RI is checking bounds as it parses the URL and not up front, which causes some inconsistent
behaviour.  There's already one work-around added to this method in order to make it more
compatible (HARMONY-2941)
> The following all throw SecurityExceptions on Harmony (when called with a handler that
is not the URL's protocol handler) where they throw StringIndexOutOfBoundsExceptions on the
RI:
> handler.parse(url, "any", 10, Integer.MIN_VALUE);
> handler.parse(url, "any", 10, Integer.MIN_VALUE+1);
> handler.parse(url, "any", Integer.MIN_VALUE, Integer.MIN_VALUE);
> handler.parse(url, "any", Integer.MIN_VALUE, 2);
