[rules-users] JUnit Test failure when Eclipse library present on classpath

[Bruno Freudensprung]

Hi,

Unfortunately I have no answer to your question.
However I actually run JUnit 4 tests calling drools 5.1.1 in Eclipse 3.5 
and it works with the following classpath. Please note that it contains 
jars that are not Drools-specific (my project-specific jars):

+- org.drools:drools-core:jar:5.1.1:compile
|  \- org.mvel:mvel2:jar:2.0.16:compile
+- org.drools:drools-api:jar:5.1.1:compile
+- org.drools:drools-compiler:jar:5.1.1:runtime
|  +- org.antlr:antlr-runtime:jar:3.1.3:runtime
|  \- org.eclipse.jdt.core.compiler:ecj:jar:3.5.1:runtime
+- org.eclipse.jdt:core:jar:3.4.2.v_883_R34x:compile
+- trove:trove:jar:2.1.0:compile
+- org.mockito:mockito-core:jar:1.8.5:test
|  +- org.hamcrest:hamcrest-core:jar:1.1:test
|  \- org.objenesis:objenesis:jar:1.0:test
+- commons-lang:commons-lang:jar:2.4:compile
+- commons-io:commons-io:jar:1.4:compile
+- org.drools:drools-ide-common:jar:5.1.1:runtime
+- org.apache.lucene:lucene-core:jar:2.3.1:runtime
+- com.thoughtworks.xstream:xstream:jar:1.3.1:runtime
|  \- xpp3:xpp3_min:jar:1.1.4c:runtime
+- log4j:log4j:jar:1.2.15:compile
|  \- javax.mail:mail:jar:1.4:compile
+- dom4j:dom4j:jar:1.6.1:compile
|  \- xml-apis:xml-apis:jar:1.0.b2:compile
+- jgrapht:jgrapht:jar:0.8.1:compile
+- org.drools:drools-bpmn2:jar:5.1.1:compile
+- jaxen:jaxen:jar:1.1-beta-4:compile
|  \- xerces:xercesImpl:jar:2.6.2:compile
\- junit:junit:jar:4.8.1:test

HTH,
Regards,

Bruno.
