静态常量不能反编译
???? 近期项目中需要反编译修改多年前的class文件，经过反编译并修改后，用Eclipse编译和java命令行得到的class文件不同，对新class文件反编译后如下：

用java命令行执行（如图）：
?
C:\j2sdk1.4.2_16\bin>javac
–classpath .;kpimodelbuild.jar;commons-logging.jar;kpimodel.jar;commons-digester.jar;sax.jar;zhibiaoutil.jar
?BasKpiDefineDaoXmlImpl.java
?
对用命令行新生成的class反编译：
?
package com.langchao.kpiengine.builder.baskpi;import com.langchao.kpiengine.model.common.BasDimensionType;import com.langchao.kpiengine.model.common.Kpi;import com.langchao.kpiengine.model.common.KpiRelation;import com.langchao.kpiengine.model.common.UnitKpi;import com.langchao.kpiengine.search.BasKpiDefine;import com.langchao.kpiengine.util.KpiConfigHelper;import com.langchao.kpiengine.xml.digester.DigesterUtil;import com.langchao.kpiengine.xml.digester.KpiDigester;import com.langchao.kpiengine.xml.digester.KpiDigesterFactory;import java.util.ArrayList;import java.util.Collection;import java.util.Iterator;import java.util.List;import java.util.Map;import org.apache.commons.logging.Log;import org.apache.commons.logging.LogFactory;public class BasKpiDefineDaoXmlImpl implements BasKpiDefineDao{ private static Log log = LogFactory.getLog("KpiQueryService"); public static final String RULE_CONFIG = BasKpiDefineDaoXmlImpl.class.getPackage().getName() + ".ruleconfig"; public static final String DEFINE_CONFIG = BasKpiDefineDaoXmlImpl.class.getName() + ".defineconfig"; private BasKpiDefine basKpiDefine;?

经比对，Eclipse生成的对应的public static final String 静态常量的值在反编译后都没有了，而使用java命令行的反编译后正常。
问题找到了，但是原因未知。
