A DESCRIPTION OF THE PROBLEM :
When the first sentence of a method is this:

    Add SQL parameter {@code ?1}, if any.

then running javadoc -breakiterator generates this broken HTML summary for the method:

    Add SQL parameter {@code ?

However, the method itself has the correct HTML generated:

    Add SQL parameter ?1, if any.



STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Create the following Java source file:

  public class Bug {

    /**
     * Add SQL parameter {@code ?1}, if any.
     */
    public String addParameter() {
        return null;
    }
  }

2. Run "javadoc -breakiterator Bug.java"

3. View the generated Bug.html. Compare Method Summary vs. Method Detail.

The generated HTML summary contains:

  <td class="colLast"><code><strong><a href="Bug.html#addParameter()">addParameter</a></strong>()</code>
  <div class="block">Add SQL parameter {@code ?</div>
  </td>


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The generated HTML summary should contain:

  <td class="colLast"><code><strong><a href="Bug.html#addParameter()">addParameter</a></strong>()</code>
  <div class="block">Add SQL parameter <code>?1</code>, if any.</div>
  </td>

ACTUAL -
The generated HTML summary contains:

  <td class="colLast"><code><strong><a href="Bug.html#addParameter()">addParameter</a></strong>()</code>
  <div class="block">Add SQL parameter {@code ?</div>
  </td>


REPRODUCIBILITY :
This bug can be reproduced always.

public class Bug {

    /**
     * Add SQL parameter {@code ?1}, if any.

}

CUSTOMER SUBMITTED WORKAROUND :
Don't use -breakiterator.
