[Jython-dev] Updating extlibs

[Stefan R. <Ste...@gm...>]

Hey all,
I spent some effort to explore feasibility of updating extlibs, especially minor versions (but sometimes even major version, e.g. guava and icu4j).
My results so far, tested with regrtest on Linux and Windows 10 using Java8 ("okay" means I did not observe additional regrtest failures):

ASM 5.0.4             -> 5.2     okay
bouncycastle:
bcpkix-jdk15on-1.54   -> 1.57    okay
bcprov-jdk15on-1.54   -> 1.57    okay

commons-compress-1.12 -> 1.14    okay
guava-20.0            -> 22.0rc1 okay
icu4j-58.1            -> 59_1    okay
Netty 4.1.6           -> 4.1.11  okay
java-sizeof-0.0.5     -- still current
jffi-1.2.13           -> 1.2.15  okay
jnr-ffi-2.1.0         -> 2.1.5   okay
jnr-netdb-1.1.6       -- still current
jnr-posix-3.0.31      -> 3.0.41  okay
jnr-constants-0.9.5   -> 0.9.9   okay
New platforms: jffi-aarch64-Linux.jar, jffi-ppc64le-Linux.jar, can be added...?
Updated various other changed platform specific jars to jffi-1.2.15 (okay as far as tested)
xercesImpl-2.11.0          -- still current
jline-2.14.2               -> 2.14.3      okay (didn't try jline-3 this time)
jarjar-1.4                 -- still current
mysql-connector-java-5.1.6 -> 5.1.42      okay
postgresql-8.3-603.jdbc4   -> 42.1.1-jre7 okay

----------These failed, so leaving them as it is:
Antlr 3.1.3                -> 3.5.2  fails
junit-4.10                 -> 4.12 or 4.11 class file for org.hamcrest.Matcher not found
(staying with 4.10 for now to avoid new dependency on hamcrest-matcher)
javax.servlet-api-2.5      -> 3.1.0  fails
mockrunner      (better don't touch; whole structure changed)
cpptasks        (better don't touch)

- will be able to test with Java 7 on Tuesday, because I left my old laptop in the office.
- will upload a fork containing these updates. Would be good if someone else could also test, especially on OSX.
Maybe some stuff was not covered by regrtests. However the chance that updates solve issues and that they create issues are probably somewhat equal and I'd prefer to focus on fixing issues with current versions rather than older ones.
So I'm strongly for getting this in if regrtests go through on Java 7 and OSX. 2.7.1RC-phase will be a good opportunity to confirm workability of these updates. Any concerns?
