JSP编译期间’tmpFile.renameTo(classFile)失败的原因’

最近,我开始在JBOss 4.0.5 JSP应用程序中遇到奇怪的行为. JSP编译在第一次(第二次,第三次,…)尝试失败,但有异常：

17:24:29,909 ERROR [[jsp]] Servlet.service() for servlet jsp threw exception
java.io.IOException: tmpFile.renameTo(classFile) failed
        at org.apache.jasper.compiler.SmapUtil$SDEInstaller.install(SmapUtil.java:245)

        at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:264)

在几次重试之后(少数是0到7),页面最终被编译并呈现OK.

平台是Windows 7-Pro 64位,Java版本是

c:\ATG\ATG2007.1>java -version
java version "1.5.0_21"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_21-b01)
Java HotSpot(TM) Client VM (build 1.5.0_21-b01, mixed mode)

JBoss版本：

16:49:51,384 INFO  [Server] Release ID: JBoss [Zion] 4.0.5.GA (build: CVSTag=Branch_4_0 date=200610162339)

Tomcat版本是5.5(JBoss附带的版本).

谢谢.

这与 Tomcat 5.5 bug 38713有关.似乎在Tomcat 5.5.25开始修复.
