thank you for the clarification. the file were written with the haskell gzip module and i assume that it writes multiple separate gzip streams. therefore i will unzip the files and then load the nt.

any hope that the jdk will update its gzip support?

In addition to Rob's point about multiple file in one GZ file...

What does the Fuseki log say?

Can you unload the NT file uncompressed?

How are you uploading the nt.gz file?

Do you know how the original GZip archive was generated?

Jena uses the standard JDK GZip support to read GZip archives. The JDK doesn’t support the case where multiple separate GZip streams are concatenated into a single file. Therefore, if the archive was created in that way Jena might only read the first stream from the archive and ignore the subsequent streams.

Extracting with rapper probably uses the OS gzip directly or a library implementation of it which does handle this concatentation

  Is this a file you could share somehow?
