StringEscapeUtils.escapeJava(String) escapes '/' characters
-----------------------------------------------------------
Key: LANG-421
URL: https://issues.apache.org/jira/browse/LANG-421
Project: Commons Lang
Issue Type: Bug
Affects Versions: 2.4
Reporter: Steve Hanmann
Priority: Blocker
Commons Lang 2.4 StringEscapeUtils.escapeJava(String) now escapes '/'
characters, which is not a valid "escapable" character in Java strings. I
haven't tried the other Java escape/unescape methods to see if they have a
similar problem, or that only Java "escapable" characters are escaped by
escapeJava(String).
This bug may have appeared as an unintended side-effect of the fix for LANG-363.
Also the javadoc for escapeJava is now a little off, in that '/' should now be
included in the sentence describing the differences between Java and Javascript
strings, with respect to escaping rules.
The following is a JUnit3 test demonstrating the bug.
import junit.framework.TestCase;
import org.apache.commons.lang.StringEscapeUtils;
public class StringEscapeUtilsTest extends TestCase {
public void testEscapeJavaWithSlash() {
final String input = "String with a slash (/) in it";
final String expected = input;
final String actual = StringEscapeUtils.escapeJava( input );
/**
* In 2.4 StringEscapeUtils.escapeJava(String) escapes '/' characters,
* which are not a valid character to escape in a Java string.
*/
assertEquals( expected, actual );
}
}
