DialectUtil.normalizeRuleName() doesn't normalize multibyte rule names ---------------------------------------------------------------------- Key: DROOLS-1192 URL: https://issues.jboss.org/browse/DROOLS-1192 Project: Drools Issue Type: Bug Components: core engine Affects Versions: 6.4.0.Final Reporter: Toshiya Kobayashi Assignee: Mario Fusco Assuming you have a rule name "rule（hello）", {noformat} package com.sample rule "rule（hello）" when then end {noformat} Here, ' （' and '）' ... U+FF08 (FULLWIDTH LEFT PARENTHESIS) and U+FF09 (FULLWIDTH RIGHT PARENTHESIS) are not a Java identifier part. The rule fails to compile. {noformat} Rule Compilation error : [Rule name='rule（hello）'] com/sample/Rule_rule（hello）0.java (3:84) : Syntax error on tokens, delete these tokens com/sample/Rule_rule（hello）0.java (3:97) : The public type Rule_rule must be defined in its own file com/sample/Rule_rule（hello）0.java (3:115) : Syntax error, insert "}" to complete Block com/sample/Rule_rule（hello）0.java (4:121) : Syntax error on tokens, delete these tokens com/sample/Rule_rule（hello）0.java (6:187) : Syntax error on token "void", @ expected com/sample/Rule_rule（hello）0.java (6:211) : Syntax error on token(s), misplaced construct(s) com/sample/Rule_rule（hello）0.java (6:238) : Syntax error on token "throws", @ expected com/sample/Rule_rule（hello）0.java (6:255) : Syntax error, insert "enum Identifier" to complete EnumHeader com/sample/Rule_rule（hello）0.java (11:332) : Syntax error on token "}", delete this token {noformat} But such a non-java identifier part should be normalized by org.drools.compiler.rule.builder.dialect.DialectUtil.normalizeRuleName() during the build. The problem is that DialectUtil.normalizeRuleName() misses to process the name because of NON_ALPHA_REGEX check. NON_ALPHA_REGEX doesn't take account into Unicode characters.
