    INT queue-length (nillable = false)
    STRING handoff-executor (nillable = true)
    BOOLEAN allow-core-timeout (nillable = true)

For Type: blocking-bounded-queue-thread-pool
    INT core-threads (nillable = true)
    INT queue-length (nillable = false)
    BOOLEAN allow-core-timeout (nillable = true)

For Type: queueless-thread-pool
    STRING handoff-executor (nillable = true)

Version-Release number of selected component (if applicable):
4.4.0.JON312GA

How reproducible:
Always

Steps to Reproduce:
1. Create a thread pool for each type: bounded-queue-thread-pool, blocking-bounded-queue-thread-pool, and queueless-thread-pool.
2. Navigate to each thread pools configuration page
