--------------------------------
Summary: StrSubstitutor.replaceSystemProperties does not work
constistently
Key: LANG-1055
URL: https://issues.apache.org/jira/browse/LANG-1055
Project: Commons Lang
Issue Type: Bug
Components: lang.text.*
Affects Versions: 3.3.2
Environment: Windows 7, Java 7
Reporter: Phil Dicke
StrSubsitutor caches a references to SystemProperties statically on first class
references. This does not work properly with System.setProperties(). For
example the following code:
{code}
package test.utilities;
import java.util.Properties;
import org.apache.commons.lang.text.StrSubstitutor;
public class TestStrSubstitutor {
public static void main(String[] args) {
System.out.println(StrSubstitutor.replaceSystemProperties("os.name=${os.name}"));
Properties testProps = new Properties();
testProps.put("test_key", "test_value");
testProps.putAll(System.getProperties());
System.setProperties(testProps);
System.out.println(StrSubstitutor.replace("test_key=${test_key}",
System.getProperties()));
System.out.println(StrSubstitutor.replaceSystemProperties("test_key=${test_key}"));
}
}
{code}
produces the following output:
{code}
os.name=Windows 7
test_key=test_value
test_key=${test_key}
{code}
The code linked here shows the static caching of the System Properties
reference:
