Tesseract: SIGSEGV in docker container when called from Java service

[duzenko]

I have a simple Java web service that I need to put in a Docker container.
It works fine on the host, but when put in a Docker container it always crashes.
Inside the container I installed tesseract via apk add --update tesseract-ocr
When running from shell it works properly, generating a text file with valid results.

Environment

• Tesseract Version: tesseract 4.0.0
• Platform: Linux a-virtual-machine 4.15.0-45-generic #48~16.04.1-Ubuntu SMP Tue Jan 29 18:03:48 UTC 2019 x86_64 Linux

Use 4.1 or 5.0 from the master branch.

How do I do that with apk?
