Nomis API Crashes here because you are running this code with a security manager
which causes FEATURE_SECURE_PROCESSING to be set in the XML parser,
when you have a really large query, it is too long for the parser with this setting set
the above reader.setProperty is an attempt to stop this from happening, but it doesn't work :(
just run the sdmx-sax jar without a security manager, this typically happens on a web server.s
