[jira] [Updated] (CALCITE-4518)
org.codehaus.commons.compiler.CompileException
[ https://issues.apache.org/jira/browse/CALCITE-4518?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
feng.huang updated CALCITE-4518:
--------------------------------
Description:
calcite call janino to compile javacode in some case such as ReduceExpressionsRule#reduceExpressions, but there is something wrong with janino handling "<" operator.
{code:java}
public static void main(String[] args) throws IOException, CompileException {
String code = "public Object[] apply(Object root0) {\n" +
"int a=1;int b=2 ; " +
"return new Object[]{a < b,1,2};\n" +
"}\n";
final ClassBodyEvaluator cbe = new ClassBodyEvaluator();
cbe.setClassName("Test");
cbe.setExtendedClass(Utilities.class);
cbe.setImplementedInterfaces(new Class[]{Function1.class, Serializable.class});
cbe.setParentClassLoader(RexExecutable.class.getClassLoader());
cbe.cook(new Scanner(null, new StringReader(code)));
}{code}
when janino read "a < b , " , it regard this as the instance of rule : ShiftExpression<TypeArgument,TypeArgument...>, and then throw "CompileException: Line 2, Column 45: IDENTIFIER expected instead of '1'.
