Tom Mueller created FELIX-4043:
----------------------------------
Summary: Make the use of SecureRandom optional for UUID generation
in Felix.init
Key: FELIX-4043
URL: https://issues.apache.org/jira/browse/FELIX-4043
Project: Felix
Issue Type: Improvement
Components: Framework
Affects Versions: framework-4.2.1
Reporter: Tom Mueller
One of the first things Felix.init does is to call Util.randomUUID to generate
the UUID that will be used by the framework. This method uses the SecureRandom
Java SE library to generate the UUID. Depending on the operating system,
initialization of SecureRandom can be very slow. For example, on Windows, this
can take hundreds of milliseconds.
When used in a single server environment, it is not clear that a UUID is even
necessary. And it may not be necessary to use one that depend on using
SecureRandom. Maybe the caller of Felix.init could provide the UUID or maybe
the UUID could be generated using Random would work just as well.
The purpose of this improvement request is to provide a method for avoiding the
use of SecureRandom when using Felix so as to reduce the time required to
initialize the Felix framework.
