Bug ID: 62286
Summary: Illegalargument exception occurrs while parsing
properties from a file that contains \u in its
property key,value
Product: Ant
Version: unspecified
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P2
Component: Core tasks
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Created attachment 35858
--> https://bz.apache.org/bugzilla/attachment.cgi?id=35858&action=edit
two files with description given in problem description
Introduction
=========================
Consider the following code snippet in ant's build.xml file
<exec dir="${basedir}"
executable="svn"
output="${basedir}/svn.properties"
failonerror="true">
<arg value="info"/>
</exec>
<property prefix="svn" file="${basedir}/svn.properties"/>
Bascially the above snippet is trying to
1. Run "svn info" command and put the output into the file "svn.properties"
2. Read the properties from the file "svn.properties" and prefix it with SVN
Problem
===========================
We get the illegalargument exception while reading the properties from the file
"svn.propeties"
Cause
=====================
The property file contains "\universal..." as part of the string.
Java's "java.util.Properties.loadconvert" api reads the '\u' character and
assumes that the character is represented as Unicode character.
But the character after '\u' is 'n' and NOT one of the hex digits.
Thus the exception is raised.
Reproduction
===================
Two files have been attached to easily reproduce and see the issue.
svn.properties - contains the properties which can generate the mentioned
issue.
TestSvnProp.java - a main file which tries to load the svn.properties
