我正在尝试将带有 Facelets 1.1.14 的 JSF 2.0 应用程序部署到 Tomcat7。我收到以下异常：

SEVERE: The web application [/AdminUI] appears to have started a thread named [Mojarra-ResourceCache-1-thread-1] but has failed to stop it. This is very likely to create a memory leak.
我在 /WEB-INF/lib/ 下有以下 jars
activation-1.1.jar
antlr-2.7.6.jar
asm-3.1.jar
cglib-2.2.jar
commons-collections-3.1.jar
dom4j-1.6.1.jar
hibernate-commons-annotations-3.2.0.final.jar
hibernate-core-3.6.5.final.jar
hibernate-entitymanager-3.6.5.final.jar
hibernate-jpa-2.0-api-1.0.0.final.jar
hibernate-validator-4.0.2.GA.jar
javassist-3.12.0.jar
jaxb-api-2.1.jar
jaxb-impl-2.1.3.jar
jsf-api-2.0.jar
jsf-impl-2.0.0.jar
jta-1.1.jar
slf4j-api-1.6.1.jar
stax-api-1.0-2.jar
如何解决这个问题？
JSF 2.0 附带了 Facelets 2.0。 Facelets 1.x JAR 文件只会与此发生冲突。你应该removeFacelets 1.x JAR 文件。
在 Tomcat 上使用 Facelets 开发 JSF 2.0 所需的所有 JAR 文件是jsf-api.jar and jsf-impl.jar.
