• Unconditionally pass the selected mapping as a request attribute under key Action.MAPPING_KEY, even if no form bean is specified.
• Avoid a NullPointerException in corner cases caused by failed initialization of ActionServlet.

The following changes and bug fixes have occurred in the file upload package (package org.apache.struts.upload):

• Fixed lost byte problem in BufferedMultipartInputStream
• Fixed ArrayIndexOutOfBoundsException situations
• Better reporting for premature closing of input streams while reading multipart requests.
• Additional fix for file corruption problem with uploads and new line characters.

The following changes and bug fixes have occurred in the utilities (package org.apache.struts.util):

• Modify RequestUtils class to use ActionServletWrapper rather than expose ActionServlet.
• ConvertUtils.convertCharacter() will now detect empty strings and return the default value.

The following changes and bug fixes have occurred in the struts-bean custom tag library (package org.apache.struts.taglib.bean):

• Correct the generated scripting variable type when the <bean:cookie>, <bean:header>, or <bean:parameter> tag is used with the "multiple" attribute.

The following changes and bug fixes have occurred in the struts-html custom tag library (package org.apache.struts.taglib.html):

• Fixed FormTag to exclude query string when identifying action mapping name.
• Correct MultiboxTagdoAfterBody() to return SKIP_BODY instead of SKIP_PAGE.
• Added the 'align' attribute to the <html:image> tag.
• On the Options tag, if the property specified by the "property" attribute returns null, it now throws an error message that indicates what the real problem is, rather than causing an NPE.
