Hello, first of all thanks to the JMeter team for the 5.4 release.
I have a small problem on Windows 10: when I load a file (either from File/Open Recent... or File/Open) an exception is logged, and "unexpected error" is displayed. It seems to be a problem with updating the recent file list Here the exception (I replaced some company info with dots). The same file can be opened with Jmeter 5.3 2020-12-08 11:06:36,340 INFO o.a.j.JMeter: Setting LAF to: laf:javax.swing.plaf.nimbus.NimbusLookAndFeel 2020-12-08 11:06:36,618 INFO o.a.j.JMeter: Loaded icon properties from org/apache/jmeter/images/icon.properties 2020-12-08 11:08:03,914 INFO o.a.j.s.FileServer: Default base='C:\Users\.....\apache-jmeter-5.4\bin' 2020-12-08 11:08:03,919 INFO o.a.j.g.a.Load: Loading file: C:\Users\.....\Documents\.......\loadtest\scripts\....\.....jmx 2020-12-08 11:08:03,919 INFO o.a.j.s.FileServer: Set new base='C:\Users\.....\Documents\.......\loadtest\scripts\....' 2020-12-08 11:08:04,120 INFO o.a.j.s.SaveService: Testplan (JMX) version: 2.2.
