I found solution. It works fine when I throw away next line from form:
enctype="multipart/form-data"
And now it pass all parameters at request ok:
<form action="/registration" method="post">
<%-- error messages --%>
<div class="form-group">
<c:forEach items="${registrationErrors}" var="error">
<p class="error">${error}</p>
</c:forEach>
</div>
