After a long testing of Aleksey’s changes i think we can say this bug is fixed now. My users are not complaining about this issue anymore.

And here’s the link to a build which includes the fix (all subsequent builds should have it too) http://bamboo.igniterealtime.org/artifact/SPARK-INSTALL4J/JOB1/build-632/Install 4j/spark_2_6_3_12555.exe

It’s build 632. Though i can’t find now in which build the patch was applied. But on the ticket Mircea says it was r13817 commit.
