# This test tests the system load average on linux and solaris.

# On windows tests if it returns -1.0 The verification is done

# by the GetSystemLoadAverage class.  By default it takes no

# input argument which verifies the system load average with

# /usr/bin/uptime command. Or specify "-1.0" as the input argument

# indicatiing that the platform doesn't support the system load average.

#Set appropriate jdk
