open-jdk 换成 sun jdk
今天在新的Linux服务器上将项目check out出来以后，重新build，就出现了下面的问题：
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-war-plugin:2.1:war (default-war) on project rendezvous: Error assembling WAR: Failed to read filesystem attributes for: /opt/dev1/test/target/test/WEB-INF/web.xml: Failed to retrieve numeric file attributes using: '/bin/sh -c l s -1nlad /opt/dev1/test/target/test/WEB-INF/web.xml': Error while executing process.

Google了一圈没有找到有用的信息，最后请教了Maven的牛人，猜测是JDK引起的。因为我安装的是Open JDK。于是抱着试试看的态度，卸载了Open JDK，然后下载安装了Sun JDK。再运行mvn package -Dmaven.test.skip=true, 真的出现了BUILD SUCCESS。
忽然想起以前好像因为Open JDK出现过其他问题，当时就换了Sun的。所以不推荐大家使用OPEN-JDK。
