爲什麼groovyc與安全管理員發生衝突？

Question

我的平臺是CentOS 7 groovy 1.8.9-7，這可能是相關的。

$ groovy -version 
Groovy Version: 1.8.9 JVM: 1.7.0_99 Vendor: Oracle Corporation OS: Linux 
$ java -version 
java version "1.7.0_99" 
OpenJDK Runtime Environment (rhel-2.6.5.0.el7_2-x86_64 u99-b00) 
OpenJDK 64-Bit Server VM (build 24.95-b01, mixed mode) 

我有一個簡單的常規文件：

#!/usr/bin/env groovy 
println System.getProperty("java.class.path") 

如果我運行它，它工作正常，如：

$ groovy info.groovy 
/usr/share/java/ant.jar:/usr/share/java/ant/ant-junit.jar:/usr/share/java/ant-launcher.jar:/usr/share/java/antlr.jar:/usr/share/java/objectweb-asm/asm.jar:/usr/share/java/objectweb-asm/asm-analysis.jar:/usr/shar 
e/java/objectweb-asm/asm-tree.jar:/usr/share/java/objectweb-asm/asm-util.jar:/usr/share/java/bsf.jar:/usr/share/java/commons-cli.jar:/usr/share/java/commons-logging.jar:/usr/share/java/groovy.jar:/usr/share/java 
/ivy.jar:/usr/share/java/jline.jar:/usr/share/java/jsp.jar:/usr/share/java/junit.jar:/usr/share/java/servlet.jar:/usr/share/java/xstream.jar:/usr/share/java/jansi.jar 

然而，groovyc的電抗器就可以了：

$ groovyc info.groovy                                       [19/472] 
>>> a serious error occurred: BUG! exception in phase 'semantic analysis' in source unit 'info.groovy' Prohibited package name: java.lang

爲什麼以及如何解決？

我沒有弄清楚確切的問題，但它似乎是我的開發環境所特有的。在新安裝的CentOS 7或RHEL 7中安裝groovy似乎工作正常。
