svn commit: r483252 - /incubator/adffaces/trunk/trinidad/trinidad-api/src/main/java/org/apache/myfaces/trinidad/util/ClassLoaderUtils.java

New Revision: 483252

URL: http://svn.apache.org/viewvc?view=rev&rev=483252
Log:
Common mistake when using ClassLoader.getResource() or getResourceAsStream() is to pass an URL that begins with a slash.  Works on some app servers, doesn't work on others.  Log a warning when this happens.
