"Out of memory!" message is untranslatable

Can confirm in 1.18 Pre-release 2. This is because the text is hardcoded in the OutOfMemoryScreen class.

Can confirm in 1.18 Pre-release 3.

Can also confirm this in 1.17.1 and 1.18 Pre-release 7. As stated above, this issue is occurring because the text is hardcoded in the OutOfMemoryScreen class.

Here's a code analysis of this issue. The following is based on a decompiled version of Minecraft 1.17.1 using MCP-Reborn.

net.minecraft.client.gui.screens.OutOfMemoryScreen.java

public class OutOfMemoryScreen extends Screen {
   public OutOfMemoryScreen() {
      super(new TextComponent("Out of memory!"));
   }
   ...
   public boolean shouldCloseOnEsc() {
      return false;
   }

   public void render(PoseStack $$0, int $$1, int $$2, float $$3) {
      this.renderBackground($$0);
      drawCenteredString($$0, this.font, this.title, this.width / 2, this.height / 4 - 60 + 20, 16777215);
      drawString($$0, this.font, "Minecraft has run out of memory.", this.width / 2 - 140, this.height / 4 - 60 + 60 + 0, 10526880);
      drawString($$0, this.font, "This could be caused by a bug in the game or by the", this.width / 2 - 140, this.height / 4 - 60 + 60 + 18, 10526880);
      drawString($$0, this.font, "Java Virtual Machine not being allocated enough", this.width / 2 - 140, this.height / 4 - 60 + 60 + 27, 10526880);
      drawString($$0, this.font, "memory.", this.width / 2 - 140, this.height / 4 - 60 + 60 + 36, 10526880);
      drawString($$0, this.font, "To prevent level corruption, the current game has quit.", this.width / 2 - 140, this.height / 4 - 60 + 60 + 54, 10526880);
      drawString($$0, this.font, "We've tried to free up enough memory to let you go back to", this.width / 2 - 140, this.height / 4 - 60 + 60 + 63, 10526880);
      drawString($$0, this.font, "the main menu and back to playing, but this may not have worked.", this.width / 2 - 140, this.height / 4 - 60 + 60 + 72, 10526880);
      drawString($$0, this.font, "Please restart the game if you see this message again.", this.width / 2 - 140, this.height / 4 - 60 + 60 + 81, 10526880);
      super.render($$0, $$1, $$2, $$3);
   }
