* Tested using poudriere testport: https://bugs.freebsd.org/bugzilla/attachment.cgi?id=162716
* Portlint -AC gives following warnings:
```
WARN: Makefile: [0]: possible direct use of command "expr" found. use ${EXPR} instead.
```
"expr" is only used in ${REINPLACE_CMD} as a match.
* Running Jython regression tests **coredumps the JVM**, but:
** Previous version hang the tests (it doesn't crash the JVM though)
** I've tried to run the tests on different systems (Cygwin, Linux) and on different JVM's (OpenJDK 7,8, Oracle 8), neither of those tries passed, I guess they're just not passable at all
