Time based recording options (time and age) are sent with a space between the value and units, e.g. "6000 ms", which may cause an issue with Java 8/Diagnostic Command.
Steps to Reproduce
Create an application with FlightRecorderDiagnosticCommandConnection which sets the 'time' or 'age' option for a recording. This causes an issue with Oracle Java 8.
Expected Result
No exception returned from the diagnostic command mbean.
Actual Result
Component version
1.36.0
Log output
com.microsoft.jfr.JfrStreamingException: Java 8 currently only supports predefined configurations (default/profile)
at com.microsoft.jfr.dcmd.FlightRecorderDiagnosticCommandConnection.formOptions(FlightRecorderDiagnosticCommandConnection.java:135)
at com.microsoft.jfr.dcmd.FlightRecorderDiagnosticCommandConnection.startRecording(FlightRecorderDiagnosticCommandConnection.java:109)
at com.microsoft.jfr.Recording.start(Recording.java:116)
Additional context
This is an issue that was reported by a third party using the com.microsoft:jfr-streaming classes, which is where jfr-connection comes from. So this issue is present in jfr-connection as well. This issue won't be fixed in com.microsoft:jfr-streaming since that code is no longer maintained.
