-------------------------------------
Hi Mark,
if this is impossible to fix for you, I can revert my commit. I did not want to
hurry anything, the bug was found by Jenkins after my commit (as I had no
chance to test this locally).
In my opinion, disabling the Morphlines tests until this is fixed is a simplier
solution than preventing the upgrade of TIKA at all, especially as more people
will use plain Solr Cell than those using Morphlines. The main problem here (as
said before) is the fact that Solr depends on an external library, that itsself
depends on an older version of Solr + a specific version of TIKA of that older
Solr version. In my opinion, to fix the whole thing completely, the morphlines
code (at least the Solr-relevant part) should also be donated to Solr and
maintained in our repository, so it fits the version of Solr.
I was also not expecting a failure, because TIKA did not change its APIs and
the compile worked perfectly fine. To me morphlines-cell was just a client to
the extracting content handler, I was not aware that it uses TIKA on its own,
bypassing extracting content handler (which is not clear from looking at the
tests). Maybe you give me a short introduction what it does in addition to Solr
Cell and why those features cannot be in Solr Cell, so people who want to use
it do not depend on Hadoop support.

> URL: https://issues.apache.org/jira/browse/SOLR-6489
> Project: Solr
> Issue Type: Bug
> Components: Tests
> Affects Versions: 4.11
> Reporter: Uwe Schindler
> Assignee: Mark Miller
> Fix For: 5.0, 4.11

>
> After upgrade tp Apache TIKA 1.6 (SOLR-6488), solr-morphlines-cell tests fail
> with scripting error messages.
> Due to missing understanding, caused by the crazy configuration file format
> and inability to figure out the test setup, I have to give up and hope that
> somebody else can take care. In addition, on my own machines, all of Hadoop
> does not work at all, so I cannot debug (Windows).
> The whole Morphlines setup is not really good, because Solr core depends on
> another TIKA version than the included morphlines libraries. This is not a
> good situation for Solr, because we should be able to upgrade to any version
> of our core components and not depend on external libraries that itsself
> depend on Solr in older versions!
