> I have seen a problem when "PdxInstanceFactory::create()" is called by several threads that are registering the same new pdx type.
> The core is produced here:
> {code}
> void PdxInstanceImpl::toDataMutable(PdxWriter& writer) {
>    auto pt = getPdxType();
>    std::vector<std::shared_ptr<PdxFieldType>>* pdxFieldList =
>        pt->getPdxFieldTypes();
> {code}
> The problem is that "getPdxType()" returns nullptr, so in the next line, there is segmentation fault when calling "pt->getPdxFieldTypes()".
> The issue can be reproduced using the attached client, and executing it using 8 threads.
