我试图使用Spring和Java 8 JDK运行一个简单的JUnit测试:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:applicationContext.xml"})
@WebAppConfiguration
public class UserServicesTest{

  @Test
  public void testJava8() {
    Set<String> strings = new HashSet<>();
    strings.add("a");
    strings.add("b");
    strings.add("c");
    strings.stream().filter(a -> a.equals("a")).forEach(p -> p.toString());
  }

我在启动时遇到了这个运行时错误:

• tomcat 7.0.16
• Java 1.6.0_22
• CentOS 5.6

我刚刚将web.xml切换到servlet 3.0(来自之前运行2.4的应用程序),现在我看到以下错误(打开了org.apache.tomcat.util的精细日志记录):

mtyson  FINE: Scanning JAR [file:/usr/java/jdk1.6.0_22/jre/lib/ext/jcharset.jar] from classpath
mtyson  Jul 19, 2011 10:04:40 AM org.apache.catalina.startup.HostConfig deployDirectory
mtyson  SEVERE: Error deploying web application directory ROOT
mtyson  org.apache.tomcat.util.bcel.classfile.ClassFormatException: Invalid byte tag in constant pool: 60

更新:刚试过tomcat 7.0.19 - 结果相同

我试图升级到Java 8时开始我们的tomcat7服务器,使用Java 7编译.war文件,我得到下面的神秘错误.

我应该期待这个吗？这篇文章说tomcat 7应该可以使用1.6及更高版本.我不知道Tomcat是应该责备还是.war.切换出我得到的不同Java版本:

• 安装JDK 7.45 - 工作(用于编译.war的相同版本)
• 安装JDK 7.55 - 失败如下
• 安装JDK 8.05 - 失败如下

是tomcat还是.war？
