From c671235ab46a0cd172550c9ae08c34b20c47b617 Mon Sep 17 00:00:00 2001 From: Minecrell Date: Mon, 18 Sep 2017 12:00:03 +0200 Subject: [PATCH] Use Log4j IOStreams to redirect System.out/err to logger Log4j2 provides an optimized implementation of PrintStream that redirects its output to a logger. Use it instead of a custom implementation for minor performance improvements and some fixes. With the old implementation, each call to System.print() results in a separate line, even though it should not result in a line break. Log4j's implementation handles it correctly. diff --git a/pom.xml b/pom.xml index d379d33d15..80359d1bf5 100644 --- a/pom.xml +++ b/pom.xml @@ -63,6 +63,11 @@ 2.8.1 runtime + + org.apache.logging.log4j + log4j-iostreams + 2.8.1 + org.ow2.asm asm diff --git a/src/main/java/net/minecraft/server/DedicatedServer.java b/src/main/java/net/minecraft/server/DedicatedServer.java index 37020dcba5..c2c676e3bb 100644 --- a/src/main/java/net/minecraft/server/DedicatedServer.java +++ b/src/main/java/net/minecraft/server/DedicatedServer.java @@ -135,8 +135,10 @@ public class DedicatedServer extends MinecraftServer implements IMinecraftServer */ // Paper end - System.setOut(new PrintStream(new LoggerOutputStream(logger, Level.INFO), true)); - System.setErr(new PrintStream(new LoggerOutputStream(logger, Level.WARN), true)); + // Paper start - Use Log4j IOStreams + System.setOut(org.apache.logging.log4j.io.IoBuilder.forLogger(logger).setLevel(Level.INFO).buildPrintStream()); + System.setErr(org.apache.logging.log4j.io.IoBuilder.forLogger(logger).setLevel(Level.WARN).buildPrintStream()); + // Paper end // CraftBukkit end thread.setDaemon(true); -- 2.21.0
