Guillaume Bourdeaux [http://community.jboss.org/people/bourdgu1304] created the discussion "does ModuleClassLoader support class array syntax?" To view the discussion, visit: http://community.jboss.org/message/626023#626023 -------------------------------------------------------------- Hi, We are having trouble deserializing rule packages on JBoss7 because JBoss7 / ModuleClassLoader 1.0.1.GA seem to ignore -Dsun.lang.ClassLoader.allowArraySyntax=true ClassLoading was working properly on JBoss6 with -Dsun.lang.ClassLoader.allowArraySyntax=true Is there any hidden option of ModuleClassLoader to reproduce native classloader behaviour and support class array syntax? Here is stacktrace: ERROR [RulePackageVersion] (MSC service thread 1-6) Could not read packaged rules: java.lang.ClassNotFoundException: [Lorg.drools.rule.Declaration; from [Module
