Does BeanShell/JSR23 Processor supports Generics(Java) in Jmeter

[Anshu Srivastava]

Below is the code i am trying to execute in Beanshell/JSR223 PreProcessor:

 line 12-         String cookie = vars.get("cookie");

 line 13-    int i = cookie.lastIndexOf('.');

 line 14-    String withoutSignature = cookie.substring(0, i + 1);

 line 15-     Jwt<Header, Claims> untrusted = Jwts.parser().parseClaimsJwt(withoutSignature); // This line does not get executed.

Below is the exception :

2016/09/06 19:44:59 ERROR - jmeter.util.BeanShellInterpreter: Error invoking bsh method: eval In file: inline evaluation of: ``import io.jsonwebtoken.Jwt; import io.jsonwebtoken.JwtBuilder; import io.jsonweb . . . '' Encountered "," at line 15, column 23.

Beanshell does not support generics so you either have to remove them like:

Jwt<Header, Claims> untrusted = Jwts.parser().parseClaimsJwt(withoutSignature);

or switch to JSR223 Sampler and Groovy language combination - it's more Java-compliant. Moreover, your test script performance will ramp up as well-developed Groovy scripts can be compiled into bytecode.

Thanks a lot for the info DT.

Hi,
Java BeanShell is some times different than classic Java

You need to remove the type for object like array, list ... because Java BeanShell auto map the type.
So you have to declare :

 line 12-         String cookie = vars.get("cookie");

 line 13-    int i = cookie.lastIndexOf('.');

 line 14-    String withoutSignature = cookie.substring(0, i + 1);

 line 15-     untrusted = Jwts.parser().parseClaimsJwt(withoutSignature); // This line does not get executed.
