RFR: 8215237: jdk.jfr.Recording javadoc does not compile

[Erik Gahlin]

Hi,

Could i have review of this docs fix that updates the example code so it 
compiles.

- It updates an incorrect method name in the Recording class.

- It rewrites the example in the consumer package so it uses the streams 
API. This makes the code tighter and avoids the use at literal in the 
javadoc comment.

Thanks
