Shift operator differs between Java and MVEL -------------------------------------------- Key: JBRULES-3112 URL: https://issues.jboss.org/browse/JBRULES-3112 Project: Drools Issue Type: Bug Security Level: Public (Everyone can see) Components: drools-compiler (expert) Affects Versions: 5.2.0.Final Reporter: Wolfgang Laun Assignee: Mark Proctor Priority: Critical Fix For: 5.3.0.Beta1 The following DRL file can be run without and with "dialect 'mvel'"; in the latter case rules 2 and 4 do not fire, otherwise all 4 rules fire. *** Using dialect Java *** test1 1 << 65552 = 10000 test1 1 << 65536 = 1 test1 1 << 65568 = 1 test2 1 << 4294967296 = 1 test2 1 << 65536 = 1 test2 1 << 65552 = 10000 test2 1 << 65568 = 1 test3 1 << 4294967296 = 1 test3 1 << 65536 = 1 test3 1 << 65552 = 10000 test4 1 << 65552 = 10000 test4 1 << 65536 = 1 *** Using dialect MVEL *** test1 1 << 65552 = 10000 test1 1 << 65536 = 1 test1 1 << 65568 = 1 test3 1 << 4294967296 = 1 test3 1 << 65536 = 1 test3 1 << 65552 = 10000 === DRL === # dialect "mvel" rule kickOff when then insert( Integer.valueOf( 1 ) ); insert( Long.valueOf( 1 ) ); insert( Integer.valueOf( 65552 ) ); // 0x10010 insert( Long.valueOf( 65552 ) ); insert( Integer.valueOf( 65568 ) ); // 0x10020 insert( Long.valueOf( 65568 ) ); insert( Integer.valueOf( 65536 ) ); // 0x10000 insert( Long.valueOf( 65536L ) ); insert( Long.valueOf( 4294967296L ) ); // 0x100000000L end rule test1 salience -1 when $a: Integer( $one: intValue == 1 ) $b: Integer( $shift: intValue ) $c: Integer( $i: intValue, intValue == ($one << $shift ) ) then System.out.println( "test1 " + $a + " << " + $b + " = " + Integer.toHexString( $c ) ); end rule test2 salience -2 when $a: Integer( $one: intValue == 1 ) $b: Long ( $shift: longValue ) $c: Integer( $i: intValue, intValue == ($one << $shift ) ) then System.out.println( "test2 " + $a + " << " + $b + " = " + Integer.toHexString( $c ) ); end rule test3 salience -3 when $a: Long ( $one: longValue == 1 ) $b: Long ( $shift: longValue ) $c: Integer( $i: intValue, intValue == ($one << $shift ) ) then System.out.println( "test3 " + $a + " << " + $b + " = " + Integer.toHexString( $c ) ); end rule test4 salience -4 when $a: Long ( $one: longValue == 1 ) $b: Integer( $shift: intValue ) $c: Integer( $i: intValue, intValue == ($one << $shift ) ) then System.out.println( "test4 " + $a + " << " + $b + " = " + Integer.toHexString( $c ) ); end -- This message is automatically generated by JIRA.
