POI 4.0 and Java 8
Hi Tika devs,
at POI, we are about to have a major change in the upcoming version after POI 3.17 is out,
which will be probably in the next week or so.
Up till now we had a discussion [1], about the next Java SE, i.e. Java 7 or 8,
and it looks like Java 8 is the preferred version - with the restriction on how you'll get along
with that decision.
In an ideal world you would say, ok we switch to Java 8 too, but I guess this won't happen ...
at least not so fast.
To continue the discussion, I could try to gather a few arguments why it would make sense
to switch, but in the end you also have upstream dependencies to check for, e.g. elasticsearch [2].
So I would choose a different approach...:
- do you have any plans to switch to Java 8? when would that be?
- if we decide to go on, how much of an impact would that be for Tika (... to rely on an older POI version)?
- any recommendations? maybe something like a mixed versions jar
Thank you,
Andi

Hi, folks.
IIRC we moved to jdk7 somewhere around 1.9-1.10. Primary issue was not to
break downstream libraries and projects of course. Same as before we will
have to make at least two releases after decision about such a migration
(to announce java 7 support deprecation in first release and migrate on
next one).
Since Oracle jdk7 get EOL status in 2015, it seems ok to migrate to jdk8 to
me. We originally discussed it as a minor goal for 2.x but its release time
frame isn't clear and, I guess, wouldn't be clear in next several months at
least.
I'd like to know what other PMCs & devs could say about downstream projects
and migration. Apache Solr requires 1.8 since 6.0 (Apr 2016), so it
wouldn't be an issue to them. Maybe someone could shed some light on other
downstream who isn't on jdk8 yet.
If there's no blockers for that I'm +1 for migrate to java 8.

Hi Tika devs,
at POI, we are about to have a major change in the upcoming version
after POI 3.17 is out, which will be probably in the next week or so.
Up till now we had a discussion [1], about the next Java SE, i.e. Java
7 or 8, and it looks like Java 8 is the preferred version - with the
restriction on how you'll get along with that decision.
In an ideal world you would say, ok we switch to Java 8 too, but I
guess this won't happen ...
at least not so fast.
To continue the discussion, I could try to gather a few arguments why
it would make sense to switch, but in the end you also have upstream
dependencies to check for, e.g. elasticsearch [2].
So I would choose a different approach...:
- do you have any plans to switch to Java 8? when would that be?
- if we decide to go on, how much of an impact would that be for Tika (...
to rely on an older POI version)?
- any recommendations? maybe something like a mixed versions jar
Thank you,
Andi

Hi, folks.
IIRC we moved to jdk7 somewhere around 1.9-1.10. Primary issue was not to
break downstream libraries and projects of course. Same as before we will
have to make at least two releases after decision about such a migration
(to announce java 7 support deprecation in first release and migrate on
next one).
Since Oracle jdk7 get EOL status in 2015, it seems ok to migrate to jdk8 to
me. We originally discussed it as a minor goal for 2.x but its release time
frame isn't clear and, I guess, wouldn't be clear in next several months at
least.
I'd like to know what other PMCs & devs could say about downstream projects
and migration. Apache Solr requires 1.8 since 6.0 (Apr 2016), so it
wouldn't be an issue to them. Maybe someone could shed some light on other

If there's no blockers for that I'm +1 for migrate to java 8.
