Sergey Chugunov updated IGNITE-5839:
------------------------------------
Description:
Simple test where {{BinaryObjectBuilder}} builder object is reused fails with
exception {noformat}org.apache.ignite.binary.BinaryObjectException: Wrong value
has been set [typeName=SimpleCls, fieldName=str, fieldType=String,
assignedValueType=Object]{noformat}
{noformat}
IgniteCache<Object, Object> cache = /* obtain a reference to
withKeepBinary cache instance */;
BinaryObjectBuilder bldr = grid(0).binary().builder("SimpleCls");
bldr.setField("str", "abc");
c.put(0, bldr.build());
bldr.setField("str", null);
c.put(1, bldr.build());
bldr.setField("str", "def");
c.put(2, bldr.build()); //exception will be thrown by call bldr.build()
{noformat}
It can be fixed by simply recreating BinaryObjectBuilder instead of reusing the
same instance.
However reusing builder object must be either explicitly prohibited or
exception must be fixed.
Right now documentation on builder class says nothing about reusing this object.
