This to avoid an UnsupportedOperationException on android 4.0 when fetching the backing array on the BoneWeight buffer. Before, only the BoneIndex was checked, and, for some mysterious reason, this ByteBuffer can be direct AND have a backing array on android 4.0. thus the preping wasn't done on the BoneWeight buffer that was kept as Direct. Hence the exception when fetching the array. git-svn-id: https://jmonkeyengine.googlecode.com/svn/trunk@9371 75d07b2b-3a1a-0410-a2c5-0572b91ccdca
