RDF4J 2.4.4

Release 2.4.4 is a patch release covering bug fixes and a workaround for an OpenJDK 8 ScheduledThreadPoolExecutor bug:

• fix for a NPE on transaction UPDATE with wrong MIME type
• fix for SPARQL function SECONDS() to also return fractions of seconds
• fix for memory leak in remote transactions

Workaround for JDK-8129861: high processor load.
Setting the property -Dorg.eclipse.rdf4j.client.executors.jdkbug will use 1 core thread (instead of 0) for clients, to avoid a 100% CPU load even when doing nothing.
