“Picked up _JAVA_OPTIONS” when no such environment variable exists

由 余生长醉 提交于 2019-11-28 12:41:23
This issue pertains specifically to Minecraft, but it is affecting all Java programs that run on my computer. It would seem that something is forcibly setting a _JAVA_OPTIONS environment variable. When I run my server, I have specified to allocate 4 GB of RAM to it with -Xms4G -Xmx4G in the startup batch file. However, when the server runs, It prints "Picked up _JAVA_OPTIONS: -Xms2048M -Xmx2048M" to the console, only allocating 2 GB. I have checked my system settings and there is no _JAVA_OPTIONS environment variable in the list. I do not want to add one, since that will also try to allocate 4

How to redirect DNS to different ports

由 不问归期 提交于 2019-11-27 19:48:16
问题 I own the domain "Arboristal.com". I also own all sub domains privately on arboristal.com. Such as lg.arboristal or ft.arboristal.com. Under my DNS settings, Arboristal.com is set to go to our web host who is currently hosting our website. I have three servers running at my house all running under one public IP address.

Constructing and sending binary data over network

问题 I am creating a command-line client for minecraft. There is a full spec on the protocol that can be found here: http://mc.kev009.com/Protocol. To answer your question beforehand, yes I am a bit of a C++ noob. I have various issues in implementing this protocol, of which each critical. The protocol says that all types are big-endian. I have no idea how I should check whether my data is little-endian and if yes how to convert to big-endian. The string datatype is a bit weird one. It's a

问题 This question already has an answer here: How can I convert my Java program to an .exe file? [closed] 13 answers I'm wondering how to package a Java application into a native binary for Windows, Linux and Mac OS X. I know Minecraft does this, but I can't figure out how. This is what'd I'd like to do: From NetBeans (preferably) or Eclipse, build the three binaries automatically. Include native libraries for OpenGL et. all. Obfuscate my code if possible. If there's some way to mimic the

Launch Minecraft from command line - username and password as prefix

由 做~自己de王妃 提交于 2019-11-26 20:26:49
问题 I'm trying to make a simple custom Minecraft launcher thing. According to the Minecraft Wiki page for the Launcher, it should be possible to run the Minecraft launcher using username and password prefixes from the command line and go directly to the game instead of through the launcher. I've tried various versions of java -cp -u=username -p=password minecraft.jar net.minecraft.LauncherFrame , and what it says is the old method: java -cp minecraft.jar net.minecraft.LauncherFrame <username>
