Janino java compiler issue -------------------------- Key: DROOLS-918 URL: https://issues.jboss.org/browse/DROOLS-918 Project: Drools Issue Type: Bug Components: core engine Affects Versions: 6.2.0.Final Reporter: sam dai Assignee: Mario Fusco Recently I upgraded drools from version 6.0.0 Final to version 6.2.0 Final, I found some bpm process can't be deployed, the error message is as below. {color:#d04437}java.lang.IllegalArgumentException: Errors while parsing knowledge base + errors added Unable to generate action invoker. Unknown variable or type "Process_org$u46$drools$u46$bpmn2$u46$90f495e7$u45$788b$u45$472c$u45$abb3$u45$b37125d5a81e_$u43$_2014$u45$06$u45$18_05$u58$40$u58$29_$u45$0700162982687" A method named "action1" is not declared in any enclosing class nor any supertype, nor through a static import Expression "Process_org$u46$drools$u46$bpmn2$u46$90f495e7$u45$788b$u45$472c$u45$abb3$u45$b37125d5a81e_$u43$_2014$u45$06$u45$18_05$u58$40$u58$29_$u45$0700162982687" is not an rvalue{color} The java compiler is "JANINO" by setting the value of system property "drools.dialect.java.compiler" as "JANINO". If I use ECLIPSE java compiler, will not have this issue. I debugged the code, found code of line 82 of org.drools.compiler.rule.builder.dialect.DialectUtil.java is changed from {color:#205081}final String newName = prefix + "_" + NON_ALPHA_REGEX.matcher(name).replaceAll("_");{color} to {color:#205081}final String newName = prefix + "_" + normalizeRuleName( name );{color} If I changed it back, bpm process can be deployed successfully. Then I did more testing. for a name "org.drools.bpmn2.fc1291c5-c25c-4c6b-aba3-76efdcd16136 + 2014-03-07 13:06:29 -0800", if I use script "normalizeRuleName( name )", the value will be "org$u46$drools$u46$bpmn2$u46$fc1291c5$u45$c25c$u45$4c6b$u45$aba3$u45$76efdcd16136_$u43$_2014$u45$03$u45$07_13$u58$06$u58$29_$u45$0800", if use script "NON_ALPHA_REGEX.matcher(name).replaceAll("_");", the value will be "org_drools_bpmn2_fc1291c5_c25c_4c6b_aba3_76efdcd16136___2014_03_07_13_06_29__0800" So I wonder if this is a bug or I missed some configuration.
