Summary: Unclear exception from BinaryObjectBuilder::build call when builder is reused Key: IGNITE-5839 URL: https://issues.apache.org/jira/browse/IGNITE-5839 Project: Ignite Issue Type: Bug Affects Versions: 2.1 Reporter: Sergey Chugunov Fix For: 2.2 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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
