Question regarding jemalloc and JVM

Is there any reason i should not be using LD_PRELOAD to force JVM use
jemalloc instead of native gcc malloc?
Background: This is for Apache-Cassandra we do off-heap cache where we
explicitly call malloc and free and by using jemalloc we see a fair amount
of space savings and was wondering if there is anything which we have to
consider before using it.
