            Reporter: Sandor Molnar

             Fix For: 2.1.0


5 years ago, when I added {{shellcheck}} support to our build in the scope of KNOX-1816, I introduced a bug in the {{findJava}} function in {{{}knox-functions.sh{}}}: when $JAVA_HOME is not set, and Java is not available on the path, the function tries to find java executables under {{{}/usr{}}}. However, the current implementation is wrong:
{noformat}
$ which java
/usr/bin/which: no java in (/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin)
$ echo $JAVA_HOME

$ bin/knoxcli.sh export-cert --type JKS
Warning: JAVA is not set and could not be found.
...  {noformat}
