Hello,
I am working on a mac os, fuseki apache-jena-fuseki-2.3.1
I increased the JVM size to:
JVM_ARGS=${JVM_ARGS:--Xmx6144M}
I have a database TDB without reasoner. I uploaded 16 million triples to it,
when I query it, i got this error :
[2016-05-16 16:43:46] Fuseki WARN [7] RC = 500 : null
java.lang.NullPointerException
