---------------------------------
Seems reasonable to me...
> NiFi launcher does not respect JAVA_HOME, fails silently
> --------------------------------------------------------
>
> Key: NIFI-416
> URL: https://issues.apache.org/jira/browse/NIFI-416
> Project: Apache NiFi
> Issue Type: Bug
> Reporter: Ricky Saltzer
>
> If you override your JAVA_HOME to another location, the nifi.sh script will
> use it, but the RunNiFi launcher will ignore it entirely. This results in a
> failure with no logging (even with verbose flag) if your default Java version
> is too old. See an example below
> {code}
> # Check Java version
> [cops@lannister-001 nifi-0.0.2-incubating-SNAPSHOT]$ java -version
> java version "1.6.0_31"
> Java(TM) SE Runtime Environment (build 1.6.0_31-b04)
> Java HotSpot(TM) 64-Bit Server VM (build 20.6-b01, mixed mode)
> # Override Java version
> [cops@lannister-001 nifi-0.0.2-incubating-SNAPSHOT]$ export
> JAVA_HOME=/usr/java/jdk1.7.0_67-cloudera/
> # Run NiFi (fails silently)
