RFR: 8303261: JFR: jdk/jfr/api/consumer/streaming/TestJVMCrash.java doesn't retry

[Erik Gahlin]

Could I have review of the test fix. Problem is that an exception is thrown when the TestProcess class tries to access the repository and the process is not available. It's unclear why this is the case, but it leads to an exception, which exits the test retry lopp. Fix is to catch the exception, print the message and retry. 

Testing. 100 * jdk/jfr/api/consumer/streaming/TestJVMCrash.java

Thanks
Erik
