When I tried to use 3rd party jar in Android Studio, I am getting java.lang.VerifyError

Question

I have spent lot of time on googling still I don't find solution to my problem. I already tried following things 1.Downgrading Gradle version. 2.Added new jar to library. 3.Clean and rebuild of project.

Tragedy is I used same jar in other two projects and it works like charm with out any issue, I already compared with other projects but could not find root cause.

What could be wrong guys?

build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion '25.0.3'

    defaultConfig {
        applicationId "garuda.GarudaMpos"
        minSdkVersion 15
        targetSdkVersion 24
        versionCode 1
        versionName "1.0.0"
        multiDexEnabled true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    dexOptions {
        incremental true
        javaMaxHeapSize "2048M"
        jumboMode = true

    }
    lintOptions{
        checkReleaseBuilds false
        abortOnError false
    }

    packagingOptions {
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/NOTICE.txt'
    }



    android {
        useLibrary 'org.apache.http.legacy'
    }


}




dependencies {
    compile files('libs/mysql-connector-java-5.0.8-bin.jar')
    compile files('libs/zbar.jar')

}

In below class i get verify error when i create Object of ScriptEngineVelocity(), this line p = new ScriptEngineVelocity();

package com.openbravo.pos.scripting;


    import android.util.Log;

    public class ScriptFactory {

        public static final String VELOCITY = "velocity";
        public static final String BEANSHELL = "beanshell";
        public static final String RHINO = "rhino";
        private static final String SHETTY = "shetty";

        /** Creates a new instance of ScriptFactory */
        private ScriptFactory() {
        }

        public static ScriptEngine getScriptEngine(String name) throws ScriptException {
            if (VELOCITY.equals(name)) {
                System.out.println("RRRRRRRRRRRRRRRRRRRRAAAAAAAAAAAAAAAAAHHHHHHHHHHH11");

                ScriptEngine p= null;
                try {
                    p = new ScriptEngineVelocity();
                } catch (ScriptException e) {
                    e.printStackTrace();
                    Log.d(SHETTY, "getScriptEngine: "+e);
                    p=null;
                }

                return p;
            } else if (BEANSHELL.equals(name)) {
                return new ScriptEngineBeanshell();

            } else {
                throw new ScriptException("Script engine not found: " + name);
            }
        }
    }

And my logcat
