IcedTea is way older than the AdoptOpenJDK initiative and the non-bin version also provides Shenandoah via additional patches applied for the build process, and some other USE flags for optional capabilities and dependencies. is going to be the better long-term replacement for the proprietary Oracle jdk? Unless it is labeled differently it doesn't seem any other distribution is using icedtea, all of their packages are labeled openjdk. I believe several other Linux distributions used to use icedtea for licensing reasons before AdoptOpenJDK was around. hth, Holger

However, openjdk has no stable version, and the ebuild contains: if use gentoo-vm ; then ewarn "WARNING! You have enabled the gentoo-vm USE flag, making this JDK" ewarn "recognised by the system. This will almost certainly break things." Which doesn't build confidence as far as using it 8-/. icedtea is pretty old. What are people doing for java needs currently? Abusing the Oracle license? Running old icedtea versions? Ignoring the openjdk warning? The warning in this form is nonsense and only ever applied to JDK > 8, since ebuilds containing java bits *might* fail due to the module system since JDK9+, nothing else. There is no notable difference between oracle-jdk-8, icedtea-8 or openjdk-8 other than IcedTea (being the JDK-8 LTS maintained by RedHat) also containing the (awesome) Shenandoah GC - which was also merged into the official upstream JDK12. IcedTea will probably (from my reading on the list) just continue the 3.x series for JDK8 and get a new series 4.x for JDK11 (since it's LTS). I offered to help with maintenance & testing but for some reason they were not interested. ¯\(ツ)/¯ It is perfectly "safe" to unmask the gentoo-vm USE flag and set openjdk-bin-8 as system VM. It is also perfectly "safe" to install openjdk-11 in parallel with said flag enabled as long as you don't set it as system VM or know what you're doing. As it happens I was just copying the openjdk-bin-11 ebuild into my local overlay as openjdk-bin-12 (because I need Shenandoah) with the gentoo-vm flag enabled and it eselects, integrates and works fine just as well. hth :) Holger

I installed icedtea-bin for now.
From the ebuild (which is a hack) I have :
DEPEND=net-misc/curl
dev-libs/cyrus-sasl
python? ( dev-lang/python dev-python/boto )
java? ( virtual/jdk )
I have seen many ebuilds, with RDEPEND=cat/pkg and
DEPEND=${RDEPEND}, I would use that. because jdk is both a runtime,
and a build time dependency in this case.
It seems would not compile until I installed the maven-bin
package..Which is not a requisite in the ebuild
but I saw that maben was a required code for building mesos on another
distro
Put maven-bin in DEPEND then, with any other build time dependency,
also there's a java-mvn-src eclass in the tree, and two other maven
related eclasses in the java overlay. check those out if you haven't
already . I have never used maven, only ant and I'm still learning
about ebuilds, so I can't say anything else.
Like I said, it's a hack, but I'll get it cleaned up; because nobody
else seemed motivated to get mesos running on gentoo.
Now it off to get spark[1] and the hadoop[2] happy on gentoo...
happy, happy happy
