JAVA_HOME is not exported for arm64 architecture

[BanzaiMan]

Curiously,

Installation | AdoptOpenJDK

does not mention $JAVA_HOME for Linux installation.

We can guess the value based on files at hand, and it would go something like this:

f=$(which javac)
while [[ -L $f ]]; do f=$(readlink $f); done
export JAVA_HOME=${f%/bin/*}

The result is something like this: https://travis-ci.org/BanzaiMan/travis_production_test/builds/641393626#L890

Could you add the snippet above in your build and see if that meets your needs?

Thanks.
