With jdk8b74, it works. If we just change the jdk to jdk8b75, then it gives the exceptions.

Steps to reproduce:
1. get a weblogic.jar, install weblogic. Note need to select 'CompleteInstall' so that the sample applications are installed.
2. cd <wls_home>/user_projects/domains/medrec/bin, execute ./startWeblogic.sh
3. to change the JVM, edit <wls_home>/user_projects/domains/medrec/bin/setDomainEnv.sh change the JAVA_HOME
