I am using the Java money reference implementation (JSR354) found here: http://javamoney.imtqy.com/ri.html
However, I use it in an OSGI environment. This gives me the following exception:
[qtp305372452-33] ERROR org.javamoney.moneta.spi.MonetaryConfig - Error loading javamoney.properties, ignoring bundleresource://7.fwk302155142:3/javamoney.properties

An exception is not thrown when using the Java money classes, but instead it is logged only. Everything works, but this exception pops up all the time in my magazines, which is very annoying for me and my colleagues.
I traced the problem to this class in the library:
package org.javamoney.moneta.spi;
public final class MonetaryConfig {
private static final Logger LOG = Logger
.getLogger(MonetaryConfig.class.getName());
private static final MonetaryConfig INSTANCE = new MonetaryConfig();
private Map<String, String> config = new HashMap<>();
private Map<String, Integer> priorities = new HashMap<>();
private MonetaryConfig() {
try {
Enumeration<URL> urls = getClass().getClassLoader().getResources(
"javamoney.properties");
while (urls.hasMoreElements()) {
URL url = urls.nextElement();
try {
Properties props = new Properties();
props.load(url.openStream());
updateConfig(props);
} catch (Exception e) {
LOG.log(Level.SEVERE,
"Error loading javamoney.properties, ignoring "
+ url, e);
}
}
} catch (IOException e) {
LOG.log(Level.SEVERE, "Error loading javamoney.properties.", e);
}
}
private void updateConfig(Properties props) {
for (Map.Entry<Object, Object> en : props.entrySet()) {
String key = en.getKey().toString();
String value = en.getValue().toString();
int prio = 0;
if (key.startsWith("{")) {
int index = key.indexOf('}');
if (index > 0) {
String prioString = key.substring(1, index);
try {
prio = Integer.parseInt(prioString);
key = key.substring(index + 1);
} catch (NumberFormatException e) {
LOG.warning("Invalid config key in javamoney.properties: " + key);
}
}
}
Integer existingPrio = priorities.get(key);
if (Objects.isNull(existingPrio)) {
priorities.put(key, prio);
config.put(key, value);
} else if (existingPrio < prio) {
priorities.put(key, prio);
config.put(key, value);
} else if (existingPrio == prio) {
throw new IllegalStateException(
"AmbiguousConfiguration detected for '" + key + "'.");
}
}
}
public static Map<String, String> getConfig() {
return Collections.unmodifiableMap(INSTANCE.config);
}
}
The updateConfig () method throws an exception. The MonetaryConfig constructor registers it. The problem arises because the row
Enumeration<URL> urls = getClass().getClassLoader().getResources(
"javamoney.properties");
