[jira] [Updated] (OAK-8212) ImporterImpl.importProperties prone to NPE

["Julian Reschke (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/OAK-8212?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Julian Reschke updated OAK-8212:
--------------------------------
    Description: 
the {{ImportImpl}} code at line 275 is prone to NPE because {{EffectiveNodeType.getPropertyDefinition(String, int, boolean)}} may return {{null}} (in contrast to the second variant that throws {{ConstraintViolationException}} if no matching definition is found.

the code looks as follows:
{code}
EffectiveNodeType ent = effectiveNodeTypeProvider.getEffectiveNodeType(tree);
PropertyDefinition def = ent.getPropertyDefinition(pi.getName(), pi.getType(), pi.isUnknownMultiple());
if (def.isProtected()) {
    ...
}
{code}

proposed fix (adding a check for null):
{code}
EffectiveNodeType ent = effectiveNodeTypeProvider.getEffectiveNodeType(tree);
PropertyDefinition def = ent.getPropertyDefinition(pi.getName(), pi.getType(), pi.isUnknownMultiple());
if (def == null) {
       throw new ConstraintViolationException("No matching property definition found for " + pi.getName());
}
if (def.isProtected()) {
    ...
}
{code}

i spotted the issue while writing an import test for OAK-8190 with property type mismatch.
