MP3 music files throwing IOException: Resetting to invalid mark

[BrockWS]

When reading certain mp3 files i get the following:

java.io.IOException: Resetting to invalid mark at java.io.BufferedInputStream.reset(BufferedInputStream.java:448) at org.tritonus.share.sampled.file.TAudioFileReader.getAudioInputStream(TAudioFileReader.java:339) at javazoom.spi.mpeg.sampled.file.MpegAudioFileReader.getAudioInputStream(MpegAudioFileReader.java:583) at javazoom.spi.mpeg.sampled.file.MpegAudioFileReader.getAudioInputStream(MpegAudioFileReader.java:493) at javax.sound.sampled.AudioSystem.getAudioInputStream(AudioSystem.java:1181) at com.ddoggy99.discordbot.handlers.MusicHandler.playMusic(MusicHandler.java:108) at com.ddoggy99.discordbot.handlers.CommandHandler.onCommandPlay(CommandHandler.java:37) at com.ddoggy99.discordbot.handlers.CommandHandler.processCommand(CommandHandler.java:87) at com.ddoggy99.discordbot.handlers.CommandHandler.onMessageReceived(CommandHandler.java:75) at net.dv8tion.jda.hooks.ListenerAdapter.onEvent(ListenerAdapter.java:178) at net.dv8tion.jda.hooks.InterfacedEventManager.handle(InterfacedEventManager.java:64) at net.dv8tion.jda.handle.MessageReceivedHandler.handleInternally(MessageReceivedHandler.java:79) at net.dv8tion.jda.handle.SocketHandler.handle(SocketHandler.java:38) at net.dv8tion.jda.requests.WebSocketClient.handleEvent(WebSocketClient.java:571) at net.dv8tion.jda.requests.WebSocketClient.onTextMessage(WebSocketClient.java:310) at com.neovisionaries.ws.client.ListenerManager.callOnTextMessage(ListenerManager.java:352) at com.neovisionaries.ws.client.ReadingThread.callOnTextMessage(ReadingThread.java:233) at com.neovisionaries.ws.client.ReadingThread.callOnTextMessage(ReadingThread.java:211) at com.neovisionaries.ws.client.ReadingThread.handleTextFrame(ReadingThread.java:910) at com.neovisionaries.ws.client.ReadingThread.handleFrame(ReadingThread.java:693) at com.neovisionaries.ws.client.ReadingThread.main(ReadingThread.java:102) at com.neovisionaries.ws.client.ReadingThread.run(ReadingThread.java:61) Caused by: java.io.IOException: Resetting to invalid mark at java.io.BufferedInputStream.reset(BufferedInputStream.java:448) at org.tritonus.share.sampled.file.TAudioFileReader.getAudioInputStream(TAudioFileReader.java:390) at org.tritonus.share.sampled.file.TAudioFileReader.getAudioInputStream(TAudioFileReader.java:329) ... 20 more

Some do work normally using mp3 and using Intellij's IDEA Debugging I can set the mark to 0 and it will then load the file fine and play it.
I am using the latest dev build 2.0.0_283 and have tried with the recommended 2.0.0_243

The FilePlayer / URLPlayer use Java SPIs. It is the SPIs fault, not JDA.
Those are example implementations and aren't very good. The Java SPIs aren't very good and are prone to failure. I would recommend using an external audio encoder/decoder like FFmpeg and writing your own AudioSendHandler implementation.
