Description

I ran thrfit  command with options "--gen java:reuse-objects" .

As a result a variable was generated with no initializing.

There are sample codes bellow.

I got a compile error that "error: variable put might not have been initialized" 

// code placeholder
@Override
 protected Object standardSchemeReadValue(org.apache.thrift.protocol.TProtocol iprot, org.apache.thrift.protocol.TField field) throws org.apache.thrift.TException {
 _Fields setField = _Fields.findByThriftId(field.id);
if (setField != null) {
switch (setField) {
case PUT:
    if (field.type == PUT_FIELD_DESC.type) {
    TPut put;
    if (put == null) {
        put = new TPut();
    }
    put.read(iprot);
