[jira] [Resolved] (JENA-858) PELLET: com.hp.hpl.jena.reasoner.BaseInfGraph.isPrepared - Change back to Protected

["Damian Steer (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/JENA-858?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Damian Steer resolved JENA-858.
-------------------------------
    Resolution: Not a Problem

This appears to have been fixed in the current pellet code base (https://github.com/clarkparsia/pellet/blob/master/jena/src/main/java/org/mindswap/pellet/jena/PelletInfGraph.java). Try pellet 2.3.2-SNAPSHOT.

(It looks like the last release was made in May 2013, so may be worth asking them to crank the handle and do another release)

>          Issue Type: Improvement
>          Components: Jena, Reasoners
>    Affects Versions: Jena 2.10.1, Jena 2.11.0, Jena 2.11.2, Jena 2.12.0, Jena 2.12.1
>         Environment: Jena with Pellet - version 2.10.1 +

> In Jena version 2.10.1 field com.hp.hpl.jena.reasoner.BaseInfGraph.isPrepared was made "private".
> This creates a runtime issue when Pellet is used.
> Pellet code makes a number of direct references to the field, which raises an IllegalAccess exception.
> It is possible to continue using older Jena versions, however it would be good to use newer and better versions of Jena where possible.
> If possible, can the field be changed back to protected?
> Ideally, this should be fixed in Pellet, but this is unlikely.
> Exception in thread "main" java.lang.IllegalAccessError: tried to access field com.hp.hpl.jena.reasoner.BaseInfGraph.isPrepared from class org.mindswap.pellet.jena.PelletInfGraph
