Full Outer Join Error

[nbauernfeind]

Description

Full outer join has a merge error due to an intermediate table having the wrong table definition.

Steps to reproduce

import io.deephaven.engine.util.TableTools
import io.deephaven.engine.util.OuterJoinTools
t1 = TableTools.timeTable("00:00:00.001").update("a = i", "b = i * 2")
t2 = TableTools.timeTable("00:00:00.001").update("a = i", "c = i * 2")
t3 = OuterJoinTools.fullOuterJoin(t1, t2, "a", "c");

Expected results

t3 should be a table that joins t1 and t2 sharing column A, and adds column C

Actual results

Internal Error 'c293970c-5f24-4451-9b26-757ec0d78c8a' io.deephaven.engine.table.TableDefinition$IncompatibleTableDefinitionException: Table definition incompatibilities:
