Legacy: 1.13 doesnt launch when offline

If use 1.13 in old launcher (1.6.89j), it works only if there is internet. If there is no internet I'm getting this in output:

 

Error: Could not find or load main class net.minecraft.client.main.Main
Java HotSpot(TM) 64-Bit Server VM warning: Using incremental CMS is deprecated and will likely be removed in a future release

 

this is 1.13 specific. Other versions works.

 

Unlike new launcher native(old) launcher works with JavaPortableLauncher (which makes Minecraft portable), so really hope that it will be fixed!
