Can Runtime.getRuntime().availableProcessors() return 0?

Is there a particular condition in which Runtime.getRuntime().availableProcessors() returns 0? Maybe when all proccessors are busy?

No. According to the docs, Runtime.availableProcessors() can never return less than one.

Returns: The maximum number of processors available to the virtual machine; never smaller than one
