The bytecode of the class does not match the source code

[魏子涵]

Hi, everyone:
      I found  the 【org.apache.flink.runtime.jobmaster.slotpool.SlotPoolImpl】 
class in【flink-runtime_2.11-1.11.1.jar】does not match the source code. Is it a 
problem we need to fix(if it is, what should we do)? or just let it go?
