Jon,

Use ICompilationUnit.getElementAt(int):

/**
* Returns the smallest element within this compilation unit that
* includes the given source position (that is, a method, field, etc.), or
* <code>null</code> if there is no element other than the compilation
* unit itself at the given position, or if the given position is not
* within the source range of this compilation unit.
*
* @param position a source position inside the compilation unit
* @return the innermost Java element enclosing a given source position or
<code>null</code>
* if none (excluding the compilation unit).
* @exception JavaModelException if the compilation unit does not exist or if
an
* exception occurs while accessing its corresponding resource
*/
IJavaElement getElementAt(int position) throws JavaModelException;

So you will have to convert your line number into a position relative to the
start of the source.

BTW, I'm don't think there is an API method such as findElements(int pos)
