I get the same error message when running a basic graph on SAR data with GPT in SNAP 8. It seems the output is unaffected but the error message is very verbose. Any ideas?
Hey,
I solved the problem by adding the line
-Djavax.xml.parsers.SAXParserFactory=com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl
to the gpt.vmoptions file.
Hope it helps
