target JVMs report a different default "toDisk" value from actual value used in new recordings

[Alexjsenn]

The default recording options can be retrieved from a target JVM using IFlightRecorderService::getAvailableRecordingOptions(). The map returned specifies the default values for different recording options. While testing (using the cjfr instance itself as a targetJVM) the JVM reports that the default value for toDisk is false. However, after creating a recording without specifying toDisk (which we assume would mean the JVM would fall back on its default), the recording is created with toDisk=true.
Given this inconsistency, the toDisk checkbox in the new recordings page of the web-client has been set to default to true, thus requiring the user to specifically disable the option if they wish to.

Hey @andrewazores, is there still something to do with issue? Just saw it mention in code:

I haven't checked the behaviour since probably when this bug was filed. In the end I think we worked around it effectively enough so it hasn't been a priority to look at it again, but perhaps the underlying bug was fixed when we upgraded JMC versions in -core? If not, then I think it's still there.
