Subject [jira] [Commented] (TIKA-888) NetCDF parser uses Java 6 JAR file and test/compilation fails with Java 1.5, although TIKA is Java 1.5
Date Fri, 30 Mar 2012 15:02:32 GMT

    [ https://issues.apache.org/jira/browse/TIKA-888?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13242408#comment-13242408

Jukka Zitting commented on TIKA-888:
------------------------------------

bq. The question is: The parser is still listed in META-INF, so when a Java 5 users tries
to parse a NetCDF file, he gets a ClassNotFound by the NetCDF parser. Whats the best way to
handle that?

By default Tika should just ignore the {{ClassNotFoundException}} in such a case, so there
should be no harm in having the NetCDF parser included in the services file.

If that doesn't work (i.e. you get an error when starting Tika), we should fix Tika to catch
the problem.

> 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).
