[nlehuby]

What steps will reproduce the problem?

Launch JOSM

Click on the Download data button

What is the expected result?

The window to download data shows up

nothing + error windows

Please provide any additional information below. Attach a screenshot if possible.

It does not seem to be specifically related to the download window: I get the same error when I try to open the relation edit window as well.

Closed as duplicate of #21059.

I don't get it: what do I need to do to be able to use JOSM again?

I still have this bug on my end, and I haven't found any information or work around to resolve my issue in the ticket marked as a duplicate.

[GerdP]

Never java versions require a lot of runtime parameters, you started JOSM without them. JOSM probably warned you about that and you ignored the warning. There are several ways to specify the run time parameters, my cfg contains these:

java-options=--add-modules
java-options=java.scripting,java.sql,javafx.controls,javafx.media,javafx.swing,javafx.web
java-options=--add-exports=java.base/sun.security.action=ALL-UNNAMED
java-options=--add-exports=java.desktop/com.sun.imageio.plugins.jpeg=ALL-UNNAMED
java-options=--add-exports=java.desktop/com.sun.imageio.spi=ALL-UNNAMED
java-options=--add-opens=java.base/java.lang=ALL-UNNAMED
java-options=--add-opens=java.base/java.nio=ALL-UNNAMED
java-options=--add-opens=java.base/jdk.internal.loader=ALL-UNNAMED
java-options=--add-opens=java.base/jdk.internal.ref=ALL-UNNAMED
java-options=--add-opens=java.desktop/javax.imageio.spi=ALL-UNNAMED
java-options=--add-opens=java.desktop/javax.swing.text.html=ALL-UNNAMED
java-options=--add-opens=java.prefs/java.util.prefs=ALL-UNNAMED

Thank you for the help. I've fixed my issue by adding a few "--add-exports" in the josm command line as instructed in the warning.
