Groovy和weblogic的classpath冲突

今天偶然运行机器上的groovy，发现启动groovysh有错：

WARNING: Abnormal JVM shutdown detected

之前我机器上没有这个错误。看到错误信息里面有weblogic的字样（第8行），随即联想到在.bashrc中设置的CLASSPATH中包含的weblogic的jar文件，如下：

1
export CLASSPATH=$CLASSPATH:$MW_HOME/wlserver/server/lib/weblogic_sp.jar:$MW_HOME/wlserver/server/lib/weblogic.jar:$MW_HOME/modules/features/weblogic.server.modules_10.3.4.0.jar:$MW_HOME/wlserver/server/lib/webservices.jar:$MW_HOME/modules/org.apache.ant_1.7.1/lib/ant-all.jar:$MW_HOME/modules/net.sf.antcontrib_1.1.0.0_1-0b2/lib/ant-contrib.jar

经过测试，这6个jar文件中，有以下3个会引起groovy的启动错误：

1
2
3
$MW_HOME/wlserver/server/lib/weblogic.jar
$MW_HOME/modules/features/weblogic.server.modules_10.3.4.0.jar
$MW_HOME/modules/org.apache.ant_1.7.1/lib/ant-all.jar

也就是说，CLASSPATH中包含其中任意一个jar文件都会导致groovy启动的错误。将它们从CLASSPATH环境变量中删除，问题就解决了。
