StringIndexOutOfBoundsException in TextureConverter when converting Farmer's Delight

[DMJXMJ]

Describe the bug

When running the latest CI builds of Hydraulic and Geyser on a Fabric 1.21.1 server, the server throws a StringIndexOutOfBoundsException during the pack conversion process for the mod "Farmer's Delight Refabricated".

This error seems to originate from TextureConverter.java:115, causing the texture conversion to fail for this mod. Consequently, Bedrock players see "Update Blocks" (question marks/dirt blocks) instead of the mod items.

Environment

Minecraft Version: 1.21.1 (Fabric)
Platform: Fabric Loader 0.18.4
Geyser Version: 2.9.2-SNAPSHOT (git-DEV-6b7ec05)
Hydraulic Version: 14300de
Farmer's Delight Version: farmersdelight 1.21.11-3.4.6+refabricated

To Reproduce

1. Install Fabric Server (Minecraft 1.21.1).
2. Install Geyser-Fabric (Build #6b7ec05) and Hydraulic (Latest CI).
3. Install "Farmer's Delight Refabricated" (version 1.21.11-3.4.6+refabricated).
4. Start the server.
5. Observe the error in the console during the Hydraulic conversion phase.

Expected behavior

Hydraulic should correctly convert the textures or gracefully handle path parsing errors without crashing the conversion thread.

# Additional Context 
I also noticed an API mismatch error in the logs, which might be related to the bleeding edge builds:
java.lang.NoClassDefFoundError: org/geysermc/geyser/api/item/custom/v2/component/java/ItemDataComponents

[SleepyPopp]

This is a known issue with Hydraulic. Hydraulic requires some changes within its codebase. Currently, nobody can do anything with Hydraulic's codebase, as Jitpack is broken and refuses to download the Custom Item API v2.

It's either Jitpack fixes itself, or we wait on Custom Item API v2 to be merged into the regular Geyser.
