[JBoss JIRA] (DROOLS-2814) MVEL uses random parameter type methods for BigDecimal.valueOf(100)

by Toshiya Kobayashi (JIRA)

Toshiya Kobayashi created DROOLS-2814: ----------------------------------------- Summary: MVEL uses random parameter type methods for BigDecimal.valueOf(100) Key: DROOLS-2814 URL: https://issues.jboss.org/browse/DROOLS-2814 Project: Drools Issue Type: Bug Components: core engine Affects Versions: 7.9.0.Final Environment: - MVEL2 2.4.0.Final Reporter: Toshiya Kobayashi Assignee: Mario Fusco When MVEL evaluates {noformat} java.math.BigDecimal.valueOf(100) {noformat} , MVEL determines a method from valueOf(double val) or valueOf(long val). The result is not consistent. Sometimes uses valueOf(double val), Sometimes uses valueOf(long val). ParseTools.getMethodScore() gives the same score for double and long. https://github.com/mvel/mvel/blob/master/src/main/java/org/mvel2/util/Par... So a selected method will depend on the order of result of "cls.getMethods()". Reproducer: $ unzip BigDecimalMvelTest.zip $ cd BigDecimalMvelTest $ mvn compile $ ./loop.sh It runs the MVEL test 100 times: {noformat} $ ./loop.sh result = 100.0 result = 100.0 result = 100.0 result = 100 result = 100.0 result = 100.0 ... {noformat} In my environment, "100.0" is the majority but randomly see "100" as well. (I couldn't reproduce with single run with java for loop) Expectation is constantly "100" (using valueOf(long val)) because in case of usual Java "java.math.BigDecimal.valueOf(100)", Java compiler chooses valueOf(long val) if the parameter is int. -- This message was sent by Atlassian JIRA (v7.5.0#75005)
