Nick Burch commented on TIKA-888:
---------------------------------
Looking a little bit more, ServiceLoader.loadStaticServiceProviders(Class) will
notify but skip over all Throwables when loading the parsers. This should cope
with invalid or missing classes that are referenced by the parser.
I wonder in this case if the NetCDF parser can be loaded just fine, but only
blows up when actually called to parse something? Is anyone with Java 1.5 able
to confirm, possibly posting the full stacktrace?
(I can't get Tika from SVN to build on Java 1.5 at the moment, it's blowing up
with some problems with Apache James Mime4J.)
If it is a problem in the parser, rather than loading the parser, then we
should either have the NetCDF parser try to use one of the ucar.nc2.NetcdfFile
classes in it's init (to trigger a quick failure during parser loading), or
have it catch more things in the parser stage itself
> NetCDF parser uses Java 6 JAR file and test/compilation fails with Java 1.5,
> although TIKA is Java 1.5

> Key: TIKA-888
> URL: https://issues.apache.org/jira/browse/TIKA-888
> Project: Tika
> Issue Type: Bug
> Components: parser
> Affects Versions: 1.0
> Reporter: Uwe Schindler
> Assignee: Chris A. Mattmann
>
> Lucene/Solr developers ran this tool before releasing Lucene/Solr 3.6 (Solr
> 3.6 is still required to run on Java 1.5, see SOLR-3295):
> http://code.google.com/p/versioncheck/
> {noformat}
> Major.Minor Version : 50.0 JAVA compatibility : Java 1.6
> platform: 45.3-50.0
> Number of classes : 60
> Classes are:
> c:\Work\lucene-solr\.\solr\contrib\extraction\lib\netcdf-4.2-min.jar [:]
> ucar/unidata/geoloc/Bearing.class
> ...
> {noformat}
> TIKA should use a 1.5 version of this class and especially do some Java 5
> tests before releasing (as it's build dependencies says, it's minimum Java5).
> I tried to compile and run TIKA tests with Java 1.5 -> crash (Invalid class
> file format).
