After verifications, it also occurs without auto-computing.

Same error on daily build 2491466a (Eclipse 2024-12 - Java 21)

added os::windows label

changed the description

not reproduced -> I've added the os::windows label

mentioned in issue #3966 (closed)

changed title from CA rows information: Null pointer exception when using "Group informations" to CA rows information: Null pointer exception when using "Group informations" or "Display coordinates"

changed the description

mentioned in commit c2cc9cf0

I set the tables as non virtual for Windows platform in c2cc9cf0

Need supplementary Windows tests.

The fix is a temporary workaround, see: #4127.
