Error when importing space to Confluence

[Jason Liu]

When I tried to use backup and restore to import a space, it showed the error. May I know why it happened?

@Jason Liu what is your JDK version? it does seem like this bug (https://bugs.openjdk.org/browse/JDK-6519463) to me.

Alternatively, what would happen if you turn off compression in your Confluence and then generate a new backup?

To turn off compression in Confluence:

1. Go to Admin>General Configuration, scroll down to the bottom, click Edit on the right, and uncheck the box next to Compress HTTP Responses

Additionally, are you uploading your backup file from UI or from <confluence-home>/restore/site ?

If the later try to do it from UI and see if that fixes the issue
