Community Consensus
Some users are unable to run the server as of 1.8.3 due to an error in utilizing the OSHI library to get processor information.
The error looks something like this:
java.lang.UnsatisfiedLinkError: Can't obtain static newInstance method for class com.sun.jna.Structure at com.sun.jna.Native.initIDs(Native Method) at com.sun.jna.Native.<clinit>(Native.java:135) at com.sun.jna.Pointer.<clinit>(Pointer.java:42) at com.sun.jna.platform.win32.WinReg$HKEY.<init>(WinReg.java:32) at com.sun.jna.platform.win32.WinReg.<clinit>(WinReg.java:61) at oshi.software.os.windows.WindowsHardwareAbstractionLayer.getProcessor s(WindowsHardwareAbstractionLayer.java:33) at net.minecraft.server.SystemUtils.<clinit>(SourceFile:16)
The code however is designed to prevent this error and fall back to "<unknown>", but it is incorrectly designed to catch Exception rather than Throwable (which an UnsatisfiedLinkError is). The fix is simply to widen the catch block in the file we name as SystemUtils from Exception to Throwable.
