Crash when attempting to auto-save the game on an encrypted drive

This crash occurs whenever the game auto-saves.

Steps to reproduce:

1. Have your .minecraft folder pointed at a drive encrypted with SecureDoc. In my case, the .minecraft folder was in its usual place on the C drive, and that drive was the one encrypted.

2. Open the game, and load a singleplayer world.

3. Soon after starting a world, it will attempt to auto-save – and will crash.

4. Or, you could press the Esc key (attempting to get the Options screen), and it will crash at that point as well.

Observations

• This happens in the net.minecraft.stats.StatisticsManagerServer.saveStatFile() method. (using MCP 9.37 naming).

• It's a NoSuchMethodError This means that while org.apache.commons.io.FileUtils.writeStringToFile(Ljava/io/File;Ljava/lang/String;) was available at compile time, it's not available at runtime in this case. Given that this environment has a full-disk-encryption suite on it, it kinda makes sense that it would be choking off access to FileUtils.

• Importantly, this is the only usage of that writeStringToFile method in the whole game, as evidenced in MCP 9.37.

  • Other file-writes use different methods, and do succeed before and after this one fails: player data, and the crash report.

Possible remedy
Notably this issue does depend on some external software messing with the system, and I understand often that takes it out of the developer's hands, but naively I can think of ways to remedy this, and I leave it to those who know better whether they are reasonable or not.

1. Attempt another way to write the stats file: avoid that writeStringToFile method, and opt for something else, like whatever's used to write the crash report or the player data.

2. Silently fail to write the stats file: There is already a catch block for an IOException, so adding a catch block for the NoSuchMethodError would silently prevent the crash.

Related ticket
On this same machine, with the same disk encryption software, using the old launcher, I used to encounter MCL-1274, which was this same NoSuchMethodError, also not finding org.apache.commons.io.FileUtils.writeStringToFile.

Thanks.
