PointPlacement with Rotation in TextSymbolizer gives NullPointerException

When trying to create a SLD 1.0.0 style through the REST-API that contains a TextSymbolizer with a PointPlacement having Rotation you get a NullPointerException from the SLDTranslator.
When creating the same SLD through the admin UI it validates fine and a correct style is created.
While debugging I found that it demands an AnchorPoint. If AnchorPoint is provided the transform succeeds. According to the XSD and documentation this should not be needed.

StyledLayerDescriptor.xsd

...
<xsd:element name="PointPlacement">
    <xsd:annotation>
      <xsd:documentation>
        A "PointPlacement" specifies how a text label should be rendered
        relative to a geometric point.
      </xsd:documentation>
    </xsd:annotation>
    <xsd:complexType>
      <xsd:sequence>
        <xsd:element ref="sld:AnchorPoint" minOccurs="0"/>
        <xsd:element ref="sld:Displacement" minOccurs="0"/>
        <xsd:element ref="sld:Rotation" minOccurs="0"/>
      </xsd:sequence>
    </xsd:complexType>
  </xsd:element>
