[slf4j-user] Does slf4j have a conflict with Spring Boot or Java Process Runtime, because it stops logging after a while

[niels]

I would guess you use the consolelogger and after a while the buffer is
full ps hangs.Without the information about the appender it's hard to
analyse.
Perhaps it would be better to call the java-program directly and not start
a java-process to start a java-process.
