Runtime exceptions in custom taglib

Question

I am getting errors of the type:
          javax.servlet.ServletException: runtime failure in custom tag
          The problem is the error is happening in a taglib, but Weblogic is hiding the
          original stack trace, and substituting it's own, which is useless in this case. Is
          there any way to get the original stack trace?

With custom tags, each interface method needs to be entirely in a try..catch
          to support debugging. WL hides the exact exception information. For
          example:
          public int doEndTag() throws JspException
          try
          catch (Throwable e)
          throw e instanceof JspException ? (JspException) e : new
          JspTagException(e.getMessage());
