NPE in parser on optional metadata ()
-------------------------------------
Key: JBRULES-1985
URL: https://jira.jboss.org/jira/browse/JBRULES-1985
Project: JBoss Drools
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: drools-compiler
Affects Versions: 5.0.0.M5
Reporter: Edson Tirelli
Assignee: Edson Tirelli
Fix For: 5.0.0.CR1
The exception:
java.lang.reflect.InvocationTargetException

Here is the drl that causes it:
[declare_type_1.drl]
package org.drools;
declare NetworkNode
locElevation: java.math.BigDecimal
name: String @key
nodeClass: String
locLongitude: java.math.BigDecimal
nodeType: String
locLatitude: java.math.BigDecimal
end
declare NetworkConnection
id: String @key
node1: NetworkNode
node2: NetworkNode
hops: Integer
end
declare NetworkEvent
@role( event )
@timestamp( creationTime )
id: String @key
locElevation: java.math.BigDecimal
description: String
sourceComponent: NetworkNode
locLongitude: java.math.BigDecimal
severity: Integer
creationTime: java.util.Date
locLatitude: java.math.BigDecimal
end
the test function in RuleParserTest.java you can use to replicate:
public void testTypeDeclaration1() throws Exception {
parseResource( "compilation_unit",
"compilation_unit",
"declare_type_1.drl" );
final PackageDescr pack = walker.getPackageDescr();
final List<TypeDeclarationDescr> declarations = pack.getTypeDeclarations();
assertEquals( 3,
declarations.size() );
}
I believe @key is the cause, I based my code on the example from the documentation:
declare Person
@author( Bob )
@dateOfCreation( 01-Feb-2009 )
name : String @key @maxLength( 30 )
dateOfBirth : Date
address : Address
end
