Transkribus 1.9.1 fails on export

[M3ssman]

Hello,

Actual Behavior

I'm facing a NPE when I try to export Transcriptions from local Files/Images as ALTO + PAGE with Transkribus 1.9.1 Client GUI and there's no data in the chosen export-Destination.

ulb-sachsen-anhalt-transkribus-1.9.1-01.zip

Expected Behavior

Export Data in PAGE and ALTO and do not yield Errors.

Please note
I've attached the root doc.xml as well as the output into the page-Subfolder which gets created in the ZIP-File. The actual TIF-File is not included

Plattform

Starting Transkribus - first trying to find java, your OS = linux-gnu
Found java executable in PATH
Java bin = java
Checking java version of: java
Java version = 1.8.0_232 (OpenJDK)

Reproduce

1. Open Folder with large Tif-Image (7346 x 10791)
2. Include some minimal Transcriptions
3. Click "Export document" => "Export options" [check also "Export ALTO", otherwise defaults] => "OK"

=> Opens Error Dialog Pane

I get the same error when trying to export PAGE.

Software used: Transkribus-1.9.1 with OpenJDK 64-Bit Server VM (build 11.0.5+10-post-Debian-2, mixed mode, sharing).

After some experiments we found a working combination with Transkribus 1.5.4 and Oracle Java 1.8.0_131-b11 to export Data as PAGE and ALTO.

On can even import existing ALTO Data and have Transkribus transform this into it's own PAGE Data, when the input ALTO is V2.

BUT

using the same Oracle Java Version as above, an update to Transkribus 1.6.0 results in a similar (silent) export issue. Looks like the client export is already broken since Version 1.6.0 ?
