AT INVOKE location specifier does not match method descriptor

radek.koubsky Aug 17, 2015 3:07 AM

Hello,

I am using AT INVOKE location specifier and it does no work in following examples:

Environment:

Byteman 3.0.1

wildfly-8.2.0.Final,

resteasy version 3.0.10.Final:

source code: byteman-wildfly-log/rest.btm at master · RadekKoubsky/byteman-wildfly-log · GitHub

1)

Here is my rule:

RULE logMethodInjectorImpl.invoke.validateAllParams

CLASS org.jboss.resteasy.core.MethodInjectorImpl

METHOD invoke(HttpRequest, HttpResponse, Object)

AT INVOKE org.jboss.resteasy.spi.validation.GeneralValidator.validateAllParameters(HttpRequest, Object, Method, Object[], Class<?>[])

IF true

DO log($CLASS, "DEBUG", "(Method invoke) Start validating all parameters of resource method, params: " + java.util.Arrays.toString($args))

ENDRULE

which should trigger at line 116 in this MethodInjectorImpl class:

GC: MethodInjectorImpl - org.jboss.resteasy.core.MethodInjectorImpl (.java) - GrepCode Class Source

Here is the target method for AT INVOKE:

public abstract void validateAllParameters(HttpRequest request, Object object, Method method, Object[] parameterValues, Class<?>... groups);

NOTE:

I replaced last parameter type Class<?>... with Class<?>[], which should work as I am using same construction for:

java.lang.reflect.Method.invoke(Object obj, Object... args) used in AT INVOVE like this:

AT INVOKE java.lang.reflect.Method.invoke(Object, Object[]) which works properly in another rule in same script.

NOTE2:

The rule above works if I use only name of the method in AT INVOKE location specifier:

AT INVOKE org.jboss.resteasy.spi.validation.GeneralValidator.validateAllParameters

However, I get exception after running bmsubmit.sh:

RULE logMethodInjectorImpl.invoke.validateAllParams

CLASS org.jboss.resteasy.core.MethodInjectorImpl

METHOD invoke(HttpRequest, HttpResponse, Object)

HELPER org.jboss.byteman.koubsky.LogHelper

AT INVOKE org.jboss.resteasy.spi.validation.GeneralValidator.validateAllParameters(HttpRequest,Object,Method,Object[],Class<?>[])

IF true

DO log($CLASS, "DEBUG", "(Method invoke) Start validating all parameters of resource method, params: " + java.util.Arrays.toString($args))

ENDRULE
