Compilation errors of Pivot trunk with Java 7 in Apache Jenkins
Hi all,
I just setup another Jenkins build of Pivot trunk, this time with Java
7 to start to look at what happens (mainly to fix some warnings if
present):
https://builds.apache.org/job/Pivot-trunk%20on%20Java%207/
Without changing settings inside build.xml the first build got some
errors ... I'll try to look at this and fix sources asap.
But could be a configuration
An extract of execution log is under.
In the meantime, if someone has suggestions ...
Bye,
Sandro

Hi Roger,
thank you very much (yes, as you I think it's an important thing to
fix) ... tomorrow I'll commit the patch, so we are really near to
2.0.2 final, for next week (the vote) :-) .
After, I re-enable the daily build even for "Pivot trunk on Java 7" in
Jenkins ... could be useful to identify other things.
Note:
the open issue (with Oracle) I have with Java 7 (all versions) on
Windows 7 at 64 bit is the only thing that really prevents me to use
it as build environment in one of my PC, but maybe with the workaround
to disable the IP v6 could make it work (I hope) ... let's update on
this.
Bye

I would say, yes, definitely before 2.1. We made (many) small API
changes for 2.0.1, so I don't imagine it will affect too many users.
And 1.7 is now "in the wild" so others will probably run into this
before too long.

Hi,
a quick update on this:
I have been able to resolve this, and in a simple way (but different
from my first proposal),
move all the Dictionary related implementation (inside Element.java)
in an inner class instance, and provide a getter method for it.
Of course this needs some little adjustements in other classes
(included in the patch), BUT even in users code ... take a look at the
patch in the issue, here:
https://issues.apache.org/jira/browse/PIVOT-855
So the real question:
I'd prefer to fix this behaviour NOW (for 2.0.2) without waiting for
the 2.1 ... what do you think ?
This is an important question, please tell me your opinions.
Unless objections I'll commit the fix tomorrow.

Hi,
the issue is this:
https://issues.apache.org/jira/browse/PIVOT-855
but the strange thing is that I don't remember compilation errors with
JDK 7 (maybe Oracle did some fix in one of latest Updates), but now
even in my alternative dev environment (using Oracle JDK 7 Update 4) I
have the same errors ... so it's not an issue related to the JDK 7
version used by Jenkins at Apache.
So I'm thinking to take a look at this, even if it's targeted to 2.1
(and maybe for 2.0.3) ...
I have to see if instead of two versions of remove methods (first
method: remove(T) in Sequence, second method: remove(K) in
Dictionary), if it's possible to make only one and split the behaviour
inside ...
Someone has objections to try to fix it before the 2.1 ?

Hi all,
some info here:
http://stackoverflow.com/questions/7201231/java-erasure-with-generic-overloading-not-overriding
Note that I just committed some small changes to our build files to
show some info at the beginning of the build ...
Probably this is a thing to fix, but in the 2.1 release, I'll make an
issue asap, to not forget it.
Bye,
Sandro
