build issues on macos 10.14

[Daan Hoogland <da...@gmail.com>]

H,
I am building directory server on macos 10.14.4 in order to try and embed
it in a Apache CloudStack test suit(, for now).

I have tried 1.5.7, 2.0.0.AM25 and latest head several times. toolchain
describes itself as below. I am pretty sure the jenv messages are not
indicative of an error. Each version shows a different error during the
build and I've been looking for a correct combination for a while now. any
help is appreciated. I finally managed to build latest head but with some
local cleans and builds (-rf options). Is there some special build
requirements in terms of JVM options that I should look at to make sure the
build succeeds without hick-ups?
Thanks in advance

$ jenv doctor

$ jenv version
