I have used Java SDK 1.6 with 1.5 compiler settings before.
I downloaded now a Java SDK 1.5 and get compile errors. Most of them are
trivial, but a few missing methods are annoying. I will create an Jira
issue.

Hi,
I just looked at the "nicer Javadoc" tutorial [1] mentioned by
Marshall. They suggest to run releases with the actual minimum JDK
version required by the project, e.g. a JDK 5 if the target version
is 1.5.
I wonder what the policy for UIMA releases. UIMA still targets Java
5, but for example on recent OS X machines Java 5 is no longer
available. So far I only set the source level in the POM of my
projects and rely on the JDK doing the right thing - so far I had no
complains. Do you consider this to be enough, or do we actually have
to get hold of some Linux an install a JDK 5 there?
This should be enough, given we have Jenkins builds running on
Java5. Those
would catch any "accidental" dependencies on post-Java-5 APIs, which
is the main
issue we've seen.
Also, what about upgrading uimaj-core to Java 6? Afaik Java 5 is no
longer officially maintained (at least by Oracle, no idea about IBM
and others). TextMarker cannot be built with Java 5 (I tried it on
Jenkins - doesn't work). The same goes for uimaFIT, although it
might be possible to step that down to 5 again - I had the
misconception that Spring 3.x was Java-6-only, but just read that it
supports Java 5 as well.
Our general posture is to upgrade to the next Java level when
"required", given
that later Java levels are OK for running UIMA as well. If we move
before we
need to, it only serves to possibly shrink (albeit perhaps very
slightly) our
user base.
If TextMarker cannot be built with Java 5, a good question to
investigate is
what it would take to make it buildable under 5. My experience is
that this is
frequently a pretty trivial change.
But if it turned out that there's some solid reason Java 6 is
required, that
could be sufficient reason to upgrade all of UIMA to 6.
I will investigate it.
