Consider the following code snippet:

IMember member = (IMember) element;
ASTParser parser = ASTParser.newParser(AST.JLS3);
Hashtable options = JavaCore.getOptions();
options.put(JavaCore.COMPILER_DOC_COMMENT_SUPPORT, JavaCore.ENABLED);
parser.setCompilerOptions(options);
parser.setKind(ASTParser.K_CLASS_BODY_DECLARATIONS);
parser.setSource(cunit);
ISourceRange range = member.getSourceRange();
if(range == null) {
  return false;
}
parser.setSourceRange(range.getOffset(), range.getLength());
ASTNode node = parser.createAST(new NullProgressMonitor());

With the source set using an ICompilationUnit (instead of a char[]) the call to createAST(..) will throw the following exception (when it shouldn't):
