Description

JSPWiki throws InternalWikiException if something really bad happenes. Currently InternalWikiException has only a constructor with String parameter, Cause and StackTrace get lost, people wonder what happened (e.g. JSPWIKI-182).

There should also be constructors with
InternalWikiException(String message, Throwable cause)

InternalWikiException extends RuntimeException which only has Throwable constructors since 1.4, probably InternalWikiException was written earlier.

With Throwable constructor, Tomcat logs the real cause:

Caused by: org.apache.wiki.api.exceptions.WikiException: JSPWiki: Unable to load and setup properties from jspwiki.properties. Failed to start. Caused by: Failed to instantiate class org.apache.wiki.PageManager; please check log files for better information.
