I've encountered a bizarre bug when a function is used together with a declared type and a rule with mvel dialect.

To reproduce create a default 'New Drools Project' in Eclipse and replace Sample.drl with the following:

--------------------------------------------------------------------------

package com.sample

function void aaa() { // <----- comment this and it will work

}

declare SomeBean

prop : int

end

rule "setup"

dialect "mvel" // <----- comment this and it will work

when

eval(true)

then

SomeBean someBean = new SomeBean();

insert(someBean);

System.out.println( "setup inserted:" + someBean);

end

rule "should never fire"

salience -20

when

not SomeBean()

then

System.out.println( "rule that should never fire fired !!!" );

end

------------------------------------------------------------------------

Run the DroolsTest.java and see that the last rule that should never fire is actually fired. If you comment out the 'aaa' function or change the dialect to 'java' all works fine.

Note that it breaks on JDK 1.5.0_12 however it works fine on JDK 1.6.0_14.

Is it just my machine or does anybody else see this issue?
