[jira] [Created] (CAMEL-10789) Indexing with simple expression
broken in Apache Camel 2.18
Surjit Sen created CAMEL-10789:
----------------------------------
Summary: Indexing with simple expression broken in Apache Camel 2.18
Key: CAMEL-10789
URL: https://issues.apache.org/jira/browse/CAMEL-10789
Project: Camel
Issue Type: Bug
Components: camel-core
Affects Versions: 2.18.2, 2.18.1, 2.18.0
Environment: Camel 2.18.0/2.18.1/2.18.2 with JDK 1.8.0_112
Reporter: Surjit Sen
Priority: Minor
Fix For: 2.18.3
The following sample code works fine with version 2.17.4 (JDK 1.7), but fails on Camel 2.18.0, 2.18.1 and 2.18.2 (JDK 1.8)
from("direct:process")
.process(new Processor() {
public void process(Exchange exchange) {
List<String> alist = new ArrayList<String>();
alist.add("1");
alist.add("99");
exchange.getIn().setHeader("ITEMS", alist);
exchange.getIn().setHeader("TOTAL_LOOPS", alist.size());
}
})
.loop(simple("${header.TOTAL_LOOPS}", Integer.class))
.setHeader("item", simple("${header.ITEMS[${property.CamelLoopIndex}]}", String.class))
.log(LoggingLevel.INFO, LOG_CLASS_NAME, simple("item = ${header.item} and TOTAL_MAPS = ${header.TOTAL_LOOPS}").getText())
.end()
.end();
With 2.18.x, the following exception gets thrown:
2017-02-03 21:13:31 ERROR DefaultErrorHandler:204 - Failed delivery for (MessageId: ID-CATL0W10D4DG4R1-55822-1486174410756-0-1 on ExchangeId: ID-CATL0W10D4DG4R1-55822-1486174410756-0-2). Exhausted after delivery attempt: 1 caught: org.apache.camel.language.bean.RuntimeBeanExpressionException: Failed to invoke method: [${property.CamelLoopIndex}] on java.util.ArrayList due to: java.lang.IndexOutOfBoundsException: Key: ${property.CamelLoopIndex} not found in bean: [1, 99] of type: java.util.ArrayList using OGNL path [[${property.CamelLoopIndex}]]
