I've just pushed a fix to master branch for ISSUE-28
make sure you have the following environment
Apache Maven 3.5.3 (3383c37e1f9e9b3bc3df5050c29c8aff9f295297; 2018-02-24T11:49:05-08:00)
Maven home: /usr/local/Cellar/maven/3.5.3/libexec
Java version: 11.0.1, vendor: Oracle Corporation
Java home: /Library/Java/JavaVirtualMachines/jdk-11.0.1.jdk/Contents/Home
Default locale: en_US, platform encoding: UTF-8
OS name: "mac os x", version: "10.11.6", arch: "x86_64", family: "mac"
e.g. a new version of Maven and running under JDK11 if possible.
My next steps are to activate the Tika EnviHeaderParser automatically... I'll post an update once done.
Thanks
Lewis
