I'm trying to transition from using JMC 6.0 from within a JDK 9 installation to using it as an Eclipse plugin, but I can't start a Flight Recorder session using the Eclipse plugin version.
This looks like a Windows-specific issue. If I open the "Start Flight Recording" wizard using 126.96.36.199920 (the plugin version), I get an error message near the top of the wizard page saying that ": is an invalid character in path C:/Users/...". It's obviously complaining about the colon after the drive letter. The path text box is read-only, and the "Browse..." button opens a dialog window that does not allow me to change the folder or path, so I'm stuck.
If I remember right, the standalone version (188.8.131.52472) gives me a relative "Destination File" path in the "Start Flight Recording" wizard, so it doesn't have this problem.
