Sulfur Cube Spawning Conditions in Java Edition Snapshot Are Out of Sync with Bedrock Edition

Description:
In the latest Java Edition snapshot where Sulfur Cubes were recently added, their spawning conditions differ significantly from those already established in Bedrock Edition. In Bedrock Edition (since beta versions 26.20.23/24), Sulfur Cubes require a block light level of 0 to spawn, use a space detection range of 0.6×1.8×0.6 (inherited from creepers), and sulfur caves do not spawn cave spiders. However, in the Java snapshot, Sulfur Cubes have no light level requirement (can spawn even at light level 15), use a proper space detection range matching their actual 0.98×0.98×0.98 collision box, and sulfur caves do spawn cave spiders. This cross-version disparity is inconsistent and disrupts farm design compatibility between the two editions.

How to Reproduce:

  1. Java Snapshot: Enter a sulfur cave biome, observe Sulfur Cube spawning behavior under different light levels, and note the presence of cave spiders.

  2. Bedrock Edition: Perform the same observations in an equivalent sulfur cave biome.

  3. Compare the results between the two versions.

Observed Result:

  • Java Snapshot: Sulfur Cubes spawn at any light level (including 15). Cave spiders spawn naturally in sulfur caves. Space detection uses the Sulfur Cube's actual size (~0.98 blocks tall).

  • Bedrock Edition: Sulfur Cubes only spawn at block light level 0; they are blocked by any light source. Cave spiders do not spawn in sulfur caves. Space detection uses creeper dimensions (1.8 blocks tall).

  • These differences create a significant parity gap, with Java's implementation being more flexible.

Expected Result:

  • Sulfur Cube spawning mechanics should be consistent between Java and Bedrock Editions.

  • Given that Bedrock's implementation has existed longer and players may have already designed farms around it, the Java snapshot should align with Bedrock's conditions (light level 0, creeper-sized space detection, no cave spiders in sulfur caves), unless the Bedrock behavior is itself considered a bug.

  • Alternatively, if Java's behavior is the intended design, Bedrock should be updated to match. Either way, parity must be achieved before full release.

Additional Notes:
The current disparity means that farm designs for sulfur caves are not cross-compatible between editions, forcing players to maintain separate designs. The difference in light level requirements is particularly impactful: Java's version allows Sulfur Cubes to spawn in well-lit areas, making them much easier to encounter and farm, while Bedrock's version restricts them to darkness only. A decision on the intended design should be made and consistently applied across both editions.
