Tapio Siilola [https://community.jboss.org/people/esiilola] created the discussion "JBoss Tools: Hibernate Tools: LGPL and EPL license conflict in the same file" To view the discussion, visit: https://community.jboss.org/message/752204#752204 -------------------------------------------------------------- Hello My perspective is that of a lawyer, so please excuse me for digging into old stuff - it merely comes with the job. :) I'm tasked with analyzing Hibernate Tools, a part of JBoss Tools, to find out its licensing. In particular, the package I need to review is an "all sources" package of JBoss Tools available at: http://downloads.sourceforge.net/jboss/JBossTools-ALL-sources-3.0.3.v2009..., (http://downloads.sourceforge.net/jboss/JBossTools-ALL-sources-3.0.3.v2009... the /hibernatetools folder contains Hibernate Tools (v.3.2.4 I believe). I understand this version of Hibernate Tools (without accounting for dependencies) is predominantly licensed with LGPL v.2.1 (or later), and parts are under Eclipse Public License 1.0. However, upon a cursory review I found two files (there may be more) which contain both the LGPL and EPL license headers. These files are: hibernatetools/plugins/org.hibernate.eclipse.mapper/src/org/hibernate/eclipse/mapper/views/contentoutline/JFaceNodeAdapterFactoryForXML.java hibernatetools/plugins/org.hibernate.eclipse.console/src/org/hibernate/eclipse/console/views/navigator/ClearPlaceHolderJob.java The EPL copyright holder is "IBM and others", while the LGPL copyright holder is JBoss. It seems to me this combination of two copyleft (albeit weak) licenses in one file may not be compatible. For the vast majority of files  in this package, when JBoss is a co-copyright owner in a file the file is distributed under the EPL license. Is this two licenses in a single file simply an oversight, and can the file be considered to be fully under one of the licenses? Or is there something else at play here, perhaps a different interpretation of the licenses, or a permission from the copyright holder? Our issue is simply wanting our forms of use/redistribution of the component to be compliant with whatever the license terms are. Here's the license header of the first file: */******************************************************************************* * Copyright (c) 2001, 2004 IBM Corporation and others. * All rights reserved.
