After I click "Play", the launcher stalls at "Downloading icu4j-core-mojang-51.2.jar".

I can't do that. I am unable to reproduce the results, but I did something before this happened. I opened my profile, changed the JVM arguments a little by adding -Xincgc to it because I heard it can reduce lag in Minecraft. Without starting Minecraft, I saved my settings and closed the launcher. I opened the launcher again and then this happened. When I started the launcher again it worked just fine.
The log files are compressed in .gz format and I don't have any programs on my computer that can extract it. I also cannot install one because I am not the administrator on my computer.
Please attach the complete output of the "Development console" which can be found on the second tab of the launcher.
