Hello, I am writing a rules file and unit tests to test each one of them. I am getting this error during the execution java.lang.VerifyError: Bad type on operand stack Exception Details: Location: ConditionEvaluator81806ffb7242407db6e6d8f829f4fd4d.evaluate(Lorg/drools/core/common/InternalFactHandle;Lorg/drools/core/common/InternalWorkingMemory;Lorg/dr ools/core/reteoo/LeftTuple;)Z @12: ireturn Reason: Type 'java/lang/Boolean' (current frame, stack[0]) is not assignable to integer Current Frame: bci: @12 flags: { } locals: { 'ConditionEvaluator81806ffb7242407db6e6d8f829f4fd4d', 'org/drools/core/common/InternalFactHandle', 'org/drools/core/common/InternalWorkingMemory', 'org/drools/core/reteoo/LeftTuple' } stack: { 'java/lang/Boolean' } Bytecode: 0000000: 2bb9 001b 0100 c000 1db6 0021 ac at java.lang.Class.getDeclaredConstructors0(Native Method) at java.lang.Class.privateGetDeclaredConstructors(Class.java:2493) at java.lang.Class.getConstructor0(Class.java:2803) at java.lang.Class.getConstructor(Class.java:1718) at org.drools.core.rule.builder.dialect.asm.ClassGenerator.newInstance(ClassGenerator.java:197) at org.drools.core.rule.constraint.ASMConditionEvaluatorJitter.jitEvaluator(ASMConditionEvaluatorJitter.java:55) at org.drools.core.rule.constraint.MvelConstraint.executeJitting(MvelConstraint.java:289) at org.drools.core.rule.constraint.MvelConstraint.access$200(MvelConstraint.java:53) at org.drools.core.rule.constraint.MvelConstraint$ConditionJitter.run(MvelConstraint.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:744) The tests don't stop running and keep working.
