ADDITIONAL SYSTEM INFORMATION : $Â uname -a Linux martin-tuxedo 5.0.0-15-generic #16-Ubuntu SMP Mon May 6 17:41:33 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux $ /home/martin/devel/jdk-13/bin/java -version openjdk version "13-ea" 2019-09-17 OpenJDK Runtime Environment (build 13-ea+23) OpenJDK 64-Bit Server VM (build 13-ea+23, mixed mode, sharing) A DESCRIPTION OF THE PROBLEM : Testing Java 13 build 23 with Apache Wicket led to a test failure in parsing an number like "3 000" with DecimalFormat. The test was passing with Java 13 build 18 and earlier versions of Java (12, 11, ...). The problem is that now ParsePosition#getIndex() returns different value if the parsed string contains Unicode characters like \u00A0. REGRESSION : Last worked in version 13 STEPS TO FOLLOW TO REPRODUCE THE PROBLEM : Execute the code below with Java 13 build 23 and any previous build: ---------- BEGIN SOURCE ---------- import java.text.DecimalFormat; import java.text.NumberFormat; import java.text.ParsePosition; import java.util.Locale; public class Java13Regression1 { public static void main(String[] args) { NumberFormat numberFormat = NumberFormat.getInstance(Locale.FRENCH); ((DecimalFormat) numberFormat).setParseBigDecimal(true); final ParsePosition position = new ParsePosition(0); String value = "3 000".replaceAll("(\\d+)\\s(?=\\d)", "$1\u00A0"); // this causes the problem numberFormat.parseObject(value, position); // prints 5 for Java 13 build 18 and earlier (Java 12, 11, ...) // But prints 1 for Java 13 build 23 System.err.println("Position index: " + position.getIndex()); } } ---------- END SOURCE ---------- FREQUENCY : always
