Apache JMeter Issue With Keystore - jmeter

Question

I am trying to use Apache JMeter 3.3 to load test an internal website. I followed the Recording tutorial mentioned on the Jmeter site (Apache JMeter HTTP(S) Test Script Recorder). I have set the following in the JMeter system.properties file to use a keystore where I have a preloaded certificate for the internal website.
javax.net.ssl.keyStore
javax.net.ssl.keyStorePassword
When I start the recorder, I get the following error in the log.
2018-02-06 21:18:57,036 INFO o.a.j.u.SSLManager: KeyStore created OK
2018-02-06 21:18:57,036 INFO o.a.j.u.SSLManager: Total of 1 aliases loaded OK from keystore

Please advise why this strange keystore error is coming up.

Most likely you have clashing configurations, JMeter's proxyserver.jks
normally doesn't require any additional setup in system.properties, default configuration should work just fine.
Just in case you need to amend JMeter's keystore configuration for any reason be aware that it is controlled via the following properties:
#---------------------------------------------------------------------------
# Test Script Recorder certificate configuration
#---------------------------------------------------------------------------
#proxy.cert.directory=<JMeter bin directory>
#proxy.cert.file=proxyserver.jks
#proxy.cert.type=JKS
#proxy.cert.keystorepass=password
#proxy.cert.keypassword=password
#proxy.cert.factory=SunX509
# define this property if you wish to use your own keystore
#proxy.cert.alias=<none>
# The default validity for certificates created by JMeter
#proxy.cert.validity=7
# Use dynamic key generation (if supported by JMeter/JVM)
# If false, will revert to using a single key with no certificate
#proxy.cert.dynamic_keys=true
The recommended way of overriding these properties is using user.properties file.
