pentaho ライブラリを使用するアプリケーションでも同じ問題が発生しました。このコードで問題を解決しました:
ケトルを初期化するシングルトン:
import org.pentaho.di.core.KettleEnvironment;
import org.pentaho.di.core.exception.KettleException;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
/**
* Inicia as configurações das variáveis de ambiente do kettle
*
* @author Marcos Souza
* @version 1.0
*
*/
public class AtomInitKettle {
private static final Logger LOGGER = LoggerFactory.getLogger(AtomInitKettle.class);
private AtomInitKettle() throws KettleException {
try {
LOGGER.info("Iniciando kettle");
KettleJNDI.protectSystemProperty();
KettleEnvironment.init();
LOGGER.info("Kettle iniciado com sucesso");
} catch (Exception e) {
LOGGER.error("Message: {} Cause {} ", e.getMessage(), e.getCause());
}
}
}
そして私を救ったコード:

import org.pentaho.di.core.exception.KettleException;

private KettleJNDI() {
}
public static void initJNDI() throws KettleException {
String path = Const.JNDI_DIRECTORY;
LOGGER.info("Kettle Const.JNDI_DIRECTORY= {}", path);
if (path == null || path.equals("")) {
try {
File file = new File("simple-jndi");
path = file.getCanonicalPath();
} catch (Exception e) {
throw new KettleException("Error initializing JNDI", e);
}
Const.JNDI_DIRECTORY = path;
LOGGER.info("Kettle null > Const.JNDI_DIRECTORY= {}", path);
}
System.setProperty("java.naming.factory.initial", "org.osjava.sj.SimpleContextFactory");
System.setProperty("org.osjava.sj.root", path);
System.setProperty("org.osjava.sj.delimiter", "/");
}
public static void protectSystemProperty() {
if (init) {
return;
}
System.setProperties(new ProtectionProperties(SYS_PROP_IC, System.getProperties()));
if (LOGGER.isInfoEnabled()) {
LOGGER.info("Kettle System Property Protector: System.properties replaced by custom properies handler");
}
init = true;
}
public static class ProtectionProperties extends Properties {
private static final long serialVersionUID = 1L;
private final String protectedKey;
public ProtectionProperties(String protectedKey, Properties prprts) {
super(prprts);
if (protectedKey == null) {
throw new IllegalArgumentException("Properties protection was provided a null key");
}
this.protectedKey = protectedKey;
}
@Override
public synchronized Object setProperty(String key, String value) {
// We forbid changes in general, but do it silent ...
if (protectedKey.equals(key)) {
if (LOGGER.isDebugEnabled()) {
LOGGER.debug("Kettle System Property Protector: Protected change to '" + key + "' with value '" + value + "'");
}
return super.getProperty(protectedKey);
}
return super.setProperty(key, value);
}
}
}
