[wtp-dev] ValidationRegistryReader problem

["Roy Ganor" <roy@xxxxxxxx>]

Sorry for the other mail…

 

Working with the latest release of WTP 3.0.1 I keep getting this exception:

 

java.lang.NullPointerException

            at org.eclipse.wst.validation.internal.ValidationRegistryReader.isConfiguredOnProject(ValidationRegistryReader.java:1056)

            at org.eclipse.wst.validation.internal.operations.ValidationOperation.setEnabledValidators(ValidationOperation.java:553)

Checking the code I think we have synchronization problem, since there is a nullity check before we get the exception:

            if (projectValidationMetaData == null)

                  projectValidationMetaData = new HashMap<IProject, Set<ValidatorMetaData>>();

 

            Set<ValidatorMetaData> vmds = projectValidationMetaData.get(project);

            if (vmds != null) {

                  return vmds.contains(vmd);

            } else {

                  Set<ValidatorMetaData> prjVmds = getValidatorMetaData(project);

                  if (prjVmds == null || prjVmds.size() == 0)return false;

                  projectValidationMetaData.put(project, prjVmds);  ß exception occurs here

                  return prjVmds.contains(vmd);

            }

 

Am I missing something?

 

Thanks,

Roy
