Andreas Haufler updated JEXL-104: --------------------------------- Attachment: JexlArithmeticBug.java FixedJexlArithmetic.java First file shows the bug. The second file is a suggested fix, BUT it is just a give re-write of the original code. I'm not too deep into reflection with arrays and all that so the original author might want to take a look at it and might apply a better fix. > NPE in JexlArithmetic when an Array-Expression containing a null is used. > ------------------------------------------------------------------------- > > Key: JEXL-104 > URL: https://issues.apache.org/jira/browse/JEXL-104 > Project: Commons JEXL > Issue Type: Bug > Affects Versions: 2.0.1 > Reporter: Andreas Haufler > Attachments: FixedJexlArithmetic.java, JexlArithmeticBug.java > > > When using the Array-Expression like [x, y, z] a NPE occurs when one of the > array elements is null. > Example: > import org.apache.commons.jexl2.Expression; > import org.apache.commons.jexl2.JexlEngine; > import org.apache.commons.jexl2.MapContext; > public class JexlArithmeticBug { > public static void main(String[] args) { > JexlEngine engine = new JexlEngine(); > String jexlExp = "[null, null]"; > Expression e = engine.createExpression(jexlExp); > System.out.println(e.evaluate(new MapContext())); > } > } > As one can see in the Stacktrace, JexlArithmetic.narrowArrayType doesn't > expect null values at all. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
