Per various differences, people download the Oracle JVM for Linux and
Windows to build on top of it; different bugs, plugin issues etc.
Various Linux distros have older versions of openjdk too btw depending
on their update strategy, so unless you want to immediately move to
their latest release for a fix in openjdk you would get those yourself.
Free/unfree OS doesn't play into it either way.
As it relates to bundling a particular version of a runtime with your
software, whether it openjdk, python, perl, etc many do it. The same
with statically linking C/C++ libraries into ones application or
distributing shareable libraries in their own folder which gets
prepended to the search path as to not be influenced by other
applications. In consumer software there is nothing much more
frustrating than trying to debug various updates to a 3rd party system
which is only affecting certain groups of ones users since they could
modify a specific component of the system you have designed or pieced
together with a single click of an update reminder. It is all about time
It comes down to a simple reality. Users don't care nor have the
understanding as to why JRE or JDK 1.6_u19 versus 1.6_u21 causes an
issue in some "unrelated" software. I know it isn't necessarily
unrelated, but try explaining to an arbitrary K-12 teacher why another
software vendor told them they had to upgrade to a different version of
the JRE/JDK and it broke another application or vice versa.
I have experienced that from both sides. So, one of their vendors has to
get in an upgrade before they are happy, and they are upset at both.
Segregate those things so they are only a component of your designed
system, and you don't have to deal with such things. What you tested is
what you have running. Yes, OS updates etc can still cause issues, but
at least one can minimise those changes.
It is what RedHat does with their professional JBoss offerings and
Apache. It makes it a turn key solution.
