> Both & org.apache.accumulo.core.file.rfile.RFileTest
have lots of failures due to calls to SEcureRandom with Random Number Generator Provider hard-coded
as Sun. The IBM JVM has it's own built in RNG Provider called IBMJCE. 2 issues - hard-coded
calls to SecureRandom.getInstance(<algo>,"SUN") and also default value in Property class
is "SUN". 
> Options for proposals:
> 1. Add mechanism to override default Property through System property through new annotator
in Property class. Only usage will be by Property.CRYPTO_SECURE_RNG_PROVIDER
> The default is SUN, as coded in the Property class. 
> Some of the unit tests explicitly call SecureRandom.getInstance() with SUN as provider.
Others rely on the default value, which is SUN (and do not rely on accumulo-site.xml in which
this can be overridden). For the system tests, I propose adding an override through a System
property. For regular execution of accumulo, accumulo-site.xml can include the adjusted default.
However, system tests will also fall on same problem.
> Another solution would be to have a factory class which supplies JVM specific behaviour,
such as default NRG provider - this could be used by the Property class to retrieve this value
based on the for java.vendor etc.....
