ISTI Open Access

It seems that also ISPC instance is affected, e.g.

https://openportal.ispc.cnr.it/browse/projects

Probably the changes to the model (ORCID) has introduced a bug.

I see that for each record, compares the following error message:

Problem parsing a mdstore record: java.lang.ArrayIndexOutOfBoundsException

I finally found the not thread safe component:

java.lang.ArrayIndexOutOfBoundsException: -1

I was using some static methods to serialise and deserialise the records and they internally were using a single instance of JAXB marshaller and unmarshaller, now the problem should be fixed.
