        Description

        The enhancement to add support for POSIX file permissions (JDK-8213031) caused significant performance regression in some situation.

        Compiler an empty class using Javac on a server with LDAP / NIS with weblogic.jar on the classpath, cause the compilation to jump from 2s to 16s.

        weblogic.jar pulls in 600+ jar files and retrieving the ownership for each of the jar files amount for 13.5 seconds of the 14 seconds regression mentioned above.
