Re: [Exist-open] Error in locally built Docker 5.3.1 image

Hi Loren,

This is a known issue/feature, not specific to eXist-db;

Something ‘ugly’ happened in the Java11 compiler regarding java.nio.ByteBuffer so if you compile eXist-db with Java11, you can not run it on Java8.

I mentioned it on the Monday teleconf actually.

There are quite many references on internet, see here <https://duckduckgo.com/?q=java.nio.ByteBuffer.clear()+java+8&t=osx&ia=web>.

On SO there is a workaround mentioned <https://stackoverflow.com/a/61267496>, but I never dared to apply it, as I did not trust it to modify so low level code. I think I remember I retracted my PR for that.

cheers

Dannes
