Fix IndexOutOfBoundsException in the initial run

[kaorahi]

1. Delete the file config.txt.
2. Start Lizzie 0.7.4.
3. Open the menu Settings > Engine and click ok button.

Then I get the following error.

Exception in thread "Thread-2" java.lang.IndexOutOfBoundsException: Index 1 out of bounds for length 1

In my environment, I have detected an error that is different from the one you suggested.
Will it be of any help?

1. Delete the file config.txt.
2. Start Lizzie 0.7.4.
3. Change the engine command./Leelaz to./Leelazero/leelaz and click the okbutton.

@hope366, I cannot reproduce your issue. Does it still occur in this? https://github.com/kaorahi/lizzie/releases/tag/patched074_210826a

If the answer is yes, would you open a new issue and show the concrete, detailed, and accurate steps of your operation?

I tried https://github.com/kaorahi/lizzie/releases/tag/patched074_210826a.

I moved the config.txt file to another location and then started Lizzie.vbs.
Naturally, an error occurred, so I ran the engine command from ./leelaz --gtp --lagbuffer 0 --weights lznetwork.gz to katago/katago-opencl gtp -config katago/default_gtp.cfg -model katago/default_model.bin. gz.
Then, the following error was reported.

Engine process ended.

        at featurecat.lizzie.analysis.Leelaz$WriterThread.run(Leelaz.java:1073)

However, this error was reported only the first time, and after the second time, it started normally without this error.
I intend to do the same operation as the first time, but for some reason the error did not occur after the second time.
