default version

[Tommy Pham]

Hello everyone,

Is there way to specify explicitly the desired Java version to build?  This
is a list of ports that I found using Java:

https://pastebin.com/PEFPyJTM

I've tried using JAVA_VERSION in make.conf based on some of the internet
search but no effect.  I resorted to patching both Mk/
bsd.default-versions.mk and Mk/bsd.java.mk.  Now I can use below in my
make.conf:

.if ${HOST_NAME} == 12_1-RELEASE-amd64-default-test
  DEFAULT_VERSIONS+=java=10
.elif ${HOST_NAME} == 12_1-RELEASE-amd64-default-test8
  DEFAULT_VERSIONS+=java=18
.elif ${HOST_NAME} == 12_1-RELEASE-amd64-default-test11
  DEFAULT_VERSIONS+=java=11
.elif ${HOST_NAME} == 12_1-RELEASE-amd64-default-test12
  DEFAULT_VERSIONS+=java=12
.elif ${HOST_NAME} == 12_1-RELEASE-amd64-default-test13
  DEFAULT_VERSIONS+=java=13
.else
  DEFAULT_VERSIONS+=java=11
.endif

to checkout any JDK as needed in poudriere:

poudriere bulk -j 12_1-RELEASE-amd64 -p default -z test13

Here are some of the random spot check of 'make java-debug':

If there isn't a way to specify the desired Java version, should I submit a
PR for this?  All of the ports needing Java that I'm using (Tomcat9,
Wildfly18, etc) all have Java 1.8+ and would build openjdk8 even though I
built openjdk11 first.


Thanks,
Tommy
