java.text.ParseException: Unparseable date: "Thu, 11 Oct, 2018 11:00:14 -0600"

stinking Java is awful at reading dates.... Let's see if the next release (32 - 31 is already in process) fixes this :-(

[grahamegrieve]

resolved - someone else ran into the same problem and tested 33 for me.

[JohannesOehm]

Unfortunatly, this is not true for me, I compiled version 33 and still got the issue.

I did some deeper digging and after some time I discovered that the way SimpleDateFormat is parsing month and weekday names is dependending on the language setting of the system. Because my computer's language is set to German, those month and weekday names are different and the parsing fails. Adding Locale.ENGLISH to the SimpleDateFormat in org.hl7.fhir.utilities.cache.PackageCacheManager#readDate resolved this issue for me.

Now, I'm experiencing another issue: Exception in thread "main" org.hl7.fhir.exceptions.FHIRException: Unable to find the package source for 'hl7.fhir.core#4.0.1' at http://hl7.org/fhir/R4/package.tgz. Is this related or should I create another ticket for this?

[grahamegrieve]

well, thanks. Stupid Java. I updated that code and looked at every use of SimpleDateFormat.

The other issue is not related. But it would be useful if you trace the source of hl7.fhir.core... it should not be used any more

It is coming from org/hl7/fhir/r4/validation/Validator.java, line 256 and is the default value in case the defn parameter is not defined.

[grahamegrieve]

oh. R4? do not use the R4 service. I've been meaning to get around to deleting it. Use the R5 code Grahame

Ah okay, I thought I'd have to use the R4 version because I'm working with R4 resources. Now, with the R5 Validator class, validation finally works. Thank You!

However, what I'm actually trying to accomplish is testing the FHIR mapping language. For the moment, I copied the script from https://www.hl7.org/fhir/patient-version-maps.html and tried to invoke the validator with C:\Users\oehmj\IdeaProjects\org.hl7.fhir.core>java -cp C:\Users\\oehmj\IdeaProjects\org.hl7.fhir.core\org.hl7.fhir.validation.cli\target\org.hl7.fhir.validation.cli-4.1.36-SNAPSHOT.jar org.hl7.fhir.r5.validation.Validator patient.fhir.json -version 4.0.1 -ig C:\Use rs\oehmj\VSCodeProjects\fhir-mapping\test.map -log out.txt -transform http://hl7.org/fhir/StructureMap/Patient4to3 -output result

The NPE mentioned in the log, which causes the validator to ignore the map file is caused by the r5....ValidationEngine#loadResourceByVersion-method creating a r4...StructureMapUtilities-Instance with null as constructur parameter for the worker-context.

I'm not sure if this is a bug or I'm just invoking the tool with the wrong command line parameters. Can You help me with this?
