FULL PRODUCT VERSION :
java version "1.8.0_144"
Java(TM) SE Runtime Environment (build 1.8.0_144-b01)
Java HotSpot(TM) 64-Bit Server VM (build 25.144-b01, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Tested both on Linux and Windows desktop OS

A DESCRIPTION OF THE PROBLEM :
I am using .jnlp file with element specifiing main JAR file (<jar href="someUrl" main="true" />).
URL used in that href atribute is one pointing to latest JAR file located in private Maven
repository (eg. http://maven.repo/search/?g=com.example&a=example-artifact&v=LATEST)

However, response to that URL is not the JAR file itself but
HTTP/1.1 307 Temporary Redirect with header Location that points to real JAR file.

Example response headers:
HTTP/1.1 307 Temporary Redirect
...
Location: http://maven.repo/com/example/example-artifact/example-artifact-0.1.jar

Java Web Start seems to fail to follow this redirect and complains
"java.util.zip.ZipException: zip file is empty".

Relevant stack trace:
