Acacia saplings do not grow on rooted dirt or moss blocks. All other saplings grow on these two blocks, including mangrove.
Steps to reproduce:
1) Place block of either moss or rooted dirt in an open area
2) Place sapling on top
3) Bonemeal the sapling.
Expected result: Tree will grow.
Actual result: Tree will grow for all saplings except Acacia.
