Robert Stupp commented on CASSANDRA-7676:
-----------------------------------------
Hm - not sure (not a shell experrt) but {{-z}} tests, if the arg is empty and
{{-x}} check if it's executable. But the first one should be sufficient.
> bin/cassandra should complain if $JAVA is empty or not an executable

> If JAVA_HOME points to a non-existing directory, bin/cassandra just complains
> with {{[node1 ERROR] /Users/snazy/.ccm/test/node1/bin/cassandra: line 151:
> exec: : not found}} (via ccm).
> Patch checks if {{$JAVA}} is empty or does not point to an executable and
> prints appropriate error message.
> (Patch against trunk)
