I first use 64bit of java and tomcat7 together with JAVA_HOME, JRE_HOME, CATALINA_HOME and CATALINA_BASE. After the first specs failed I used 32bit of java and tomcat7 together with JAVA_HOME, JRE_HOME, CATALINA_HOME and CATALINA_BASE. And it's giving the same set of errors. Maybe it's not because of simultanous installation of 32bit and 64bit versions of java. I also used both 32bit and 64bit versions when I was using windows 7 and it works. I remember the first time I encounter this ERROR was when I didn't stop tomcat before I run js-install-ce.bat. I'm not able to investigate import-minimal-ce because I don't really know how it works. js-install-ce.bat test always resulting to BUILD SUCCESSFULL.
