      Description

      A NPE occurs when a metadata binary rule is overriden without mentioning the order attribute.

      How to reproduce:

      • start a 10.10 instance with nuxeo-dam addon installed and the following XML contribution deployed (e.g. in $NUXEO_HOME/nxserver/config/): 
        <require>org.nuxeo.ecm.platform.picture.binary.metadata.contrib</require>

<extension point="metadataRules" target="org.nuxeo.binary.metadata" >
    <rule id="iptc" enabled="false" />
</extension>

      Expected result: the rule gets overriden and gets disabled
      Actual result: the following error occurs and compoment org.nuxeo.binary.metadata is unstarted:

      Workaround:
      add the order attribute (with the same value as the original one) to the overriding rule:

      <require>org.nuxeo.ecm.platform.picture.binary.metadata.contrib</require>

<extension point="metadataRules" target="org.nuxeo.binary.metadata" >
    <rule id="iptc" order="0" enabled="false" />
