A recent bug fix illustrates that if JAVA\_HOME is not defined at startup,
the system uses whatever it can find with "whatever?" path it is using.
Note the following insufficient documentation statement:
\*The version of Java that will be used can be set by setting the JAVA\_HOMEenvironment variable.
\*
Its not acceptable that an Enterprise shop should have dig through source
code to determine why this isn't working. Hence I suggest the following
change: someone open an issue on the dev community requesting that 1) is
JAVA\_HOME is found it is declared in the logs, and the version is printed,
2) if note found, message again with the location of the java that _was_
found and print its version.
I have decades of experience with enterprise search shops; and search shops
alone. This doesn't meet my need for certifying to Network Ops.
? thoughts ?

Hello!
What wait for someone to open the issue, when you can do it yourself ? Just to to [https://github.com/elasticsearch/elasticsearch/issues](https://github.com/elasticsearch/elasticsearch/issues) and create a new issue there.
