[logback-user] RollingFileAppender not writing to disk...

27 Jul 2020


      Using logback 1.2.3 in Spring Boot 2.3.2. What I'm seeing is that upon
startup, the file is created with size 0 and doesn't flush. The default
buffer size is 8k, no? Shouldn't it flush every 8k? If I close my app, then
the logfile is written (about 17k). Logback-spring.xml is below. This is on
Windows 10 x64.

<!DOCTYPE configuration>

       <include resource="org/springframework/boot/logging/logback/base.xml"
