I found an article (Unable to add attachments or view existing attachment after server migration) with similar symptoms, and the error: 

Could not initialize class com.atlassian.plugins.conversion.convert.image.ImagingConverter

If the attachment has fonts that are not installed on the server you should be able to find an entry in the log like:

FontFamily 'Font_Name' not found

 You will need to install the font on the OS level to resolve that.

Thank you, but i solved problem. Problem was be with that in docker need create image with oracle java 8 and dont use openjdk 8.
