| Summary: | org.apache.catalina.loader.WebappClassLoader throws exception related to Java 6 Bug 6434149 | ||
|---|---|---|---|
| Product: | Tomcat 5 | Reporter: | Eduardo Torres-Pardo <eduardo.torres-pardo> |
| Component: | Catalina | Assignee: | Tomcat Developers Mailing List <dev> |
| Status: | RESOLVED FIXED | ||
| Severity: | normal | ||
| Priority: | P2 | ||
| Version: | 5.5.27 | ||
| Target Milestone: | --- | ||
| Hardware: | PC | ||
| OS: | Windows XP | ||
I've fixed this in trunk but won't be proposing it for backport to 6.0.x or 5.5.x. For those versions you can use setenv.sh|bat to configure -Dsun.lang.ClassLoader.allowArraySyntax=true |
Our application uses JSF. Upon defining navigation with NavigationRuleRule, we get the exception WARN NavigationRuleRule - [NavigationRuleRule]{faces-config/navigation-rule} Me rge(*) java.lang.ClassNotFoundException: [Ljava.lang.String; at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoa der.java:1352) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoa der.java:1198) at com.sun.faces.config.ConfigureListener.configure(ConfigureListener.ja va:615) at com.sun.faces.config.ConfigureListener.configure(ConfigureListener.ja va:402) at com.sun.faces.config.ConfigureListener.contextInitialized(ConfigureLi stener.java:328) at org.apache.catalina.core.StandardContext.listenerStart(StandardContex t.java:3729) at org.apache.catalina.core.StandardContext.start(StandardContext.java:4 187) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1013) at org.apache.catalina.core.StandardHost.start(StandardHost.java:718) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1013) at org.apache.catalina.core.StandardEngine.start(StandardEngine.java:442 ) at org.apache.catalina.startup.Embedded.start(Embedded.java:821) This is due to Java 6 Bug 6434149 (http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6434149) This link recommends the following actions to solve this bug: 1) Add -Dsun.lang.ClassLoader.allowArraySyntax=true if you want to use a library for which you don't have the source with JDK6 2) Change loader.loadClass( name ) to Class.forName( name, false, loader ) if you own the code. class org.apache.catalina.loader.WebAppClassLoader uses this code to load classes: clazz = loader.loadClass(name); Can you please change the sections of code where this line is used (1352 and others) to clazz = Class.forName( name, false, loader); so this problem is solved? Thanks
