JBRULES-1348 introduces a bug in interaction between CompositeObjectSinkAdapter$HashKey and BaseObjectClassFieldReader
be following code change

• } else if ( vtype.isIntegerNumber() ) { + }

  else if ( vtype.isIntegerNumber() || vtype.isChar() ) {
  this.type = LONG;
  if ( !isNull ) {
  this.lvalue = extractor.getLongValue( null, value );

because BaseObjectClassFieldReader.getLongValue() doesn't handle properties of Character type,
and RuntimeDroolsException is thrown with message "Conversion to double not supported from java.lang.Character".

In case BaseObjectClassFieldReader.getLongValue() returns ((Character) value).charValue() instead of throwing exception,
exception in the following form will be thrown be CompositeObjectSinkAdapter$HashKey
on equality check if other HashKey gained type OBJECT instead of LONG:
