Exception in hash code calculation for character attributes in alpha hashing optimization ----------------------------------------------------------------------------------------- Key: JBRULES-2466 URL: https://issues.jboss.org/browse/JBRULES-2466 Project: Drools Issue Type: Sub-task Security Level: Public(Everyone can see) Components: drools-core (expert) Affects Versions: 5.1.0.M1 Reporter: Olexandr Demura Assignee: Mark Proctor Fix For: 5.2.0.CR1 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: java.lang.NumberFormatException: For input string: "R" at java.lang.NumberFormatException.forInputString(NumberFormatException.java:48) at java.lang.Long.parseLong(Long.java:403) at java.lang.Long.parseLong(Long.java:461) at org.drools.reteoo.CompositeObjectSinkAdapter$HashKey.getLongValue(CompositeObjectSinkAdapter.java:628) at org.drools.reteoo.CompositeObjectSinkAdapter$HashKey.equals(CompositeObjectSinkAdapter.java:692) at org.drools.util.AbstractHashTable$EqualityEquals.equal(AbstractHashTable.java:446) at org.drools.util.ObjectHashMap.get(ObjectHashMap.java:90) at org.drools.reteoo.CompositeObjectSinkAdapter.propagateAssertObject(CompositeObjectSinkAdapter.java:326)
