-----------------------------------
Summary: org.codehaus.commons.compiler.CompileException
Key: CALCITE-4518
URL: https://issues.apache.org/jira/browse/CALCITE-4518
Project: Calcite
Issue Type: Bug
Reporter: feng.huang
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...>.
