Why I am getting Java lang abstractmethoderror errors?

Question

Below is the error I get: 

Exception in thread "pool-1-thread-1" java.lang.AbstractMethodError:

org.apache.thrift.ProcessFunction.isOneway()Z

    at org.apache.thrift.ProcessFunction.process(ProcessFunction.java:51)

    at org.apache.thrift.TBaseProcessor.process(TBaseProcessor.java:39)

    at com.gemfire.gemstone.thrift.hbase.ThreadPoolServer$ClientConnnection.run(Unknown Source)

    at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886)

    at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908)

    at java.lang.Thread.run(Thread.java:662)

Can anyone tell me what’s the reason for the AbstractMethodError? 

Answer 1

The reason you get this error, a part of your code tries to call a method which is declared abstract. Since abstract methods don't have a body it cannot be executed.
