Problem with abstracts in the jams-l document class

Question

I am preparing a submission to the Journal of the American Mathematical Society, and I'm using the jams-l document class. However, the abstract always appears after the body of my article text. Anyone knows how to move the abstract to the front, or am I doing something wrong? Here's some sample code where it happens. Sorry for the long code but I tried to not to delete anything that might have caused it. To load it, one needs the jams-l.cls package.

\documentclass{jams-l}

\newtheorem{theorem}{Theorem}[section]
\newtheorem{lemma}[theorem]{Lemma}

\theoremstyle{definition}
\newtheorem{definition}[theorem]{Definition}
\newtheorem{example}[theorem]{Example}
\newtheorem{xca}[theorem]{Exercise}

\theoremstyle{remark}
\newtheorem{remark}[theorem]{Remark}

\numberwithin{equation}{section}

Answer 1

A comment in the class file says

% Set abstract at the end of the paper instead of the topmatter section

This means that the abstract at the end is what the staff at the Journal of AMS wants it to be. Since you're required to use that class, leave the abstract where they want it to appear.
