java.port.mk oddness (?)

[Pascal Stumpf]

Hi ports@,

found the following in devel/jdk/java.port.mk:

[...]

.elif ${MODJAVA_VER} == "1.3+" || ${MODJAVA_VER} == "1.4+"
   ONLY_FOR_ARCHS?= i386 amd64
.  if ${NO_BUILD:L} != "yes"
     JAVA_HOME= ${LOCALBASE}/jdk-1.5.0
     BUILD_DEPENDS+= jdk->=1.5.0,<1.6:devel/jdk/1.5
.  endif

[...]

So, I’m curious: Why would MODJAVA_VER = 1.[34]+ imply ‘jdk 1.5 only’?
This behaviour is essentially the same for 1.[56]+ too, setting
RUN_DEPENDS as expected but forcing a specific jdk version for
BUILD_DEPENDS. Can someone please explain if/why this is intended?

IMO, for MODJAVA_VER = x.y+, it should detect whether a jdk is already
present on the system, and use that as both BUILD_DEPENDS and
RUN_DEPENDS (and if not, prompt the user to install the jdk-1.7 package).

Cheers,
Pascal
