  *** java.lang.instrument ASSERTION FAILED ***: "!errorOutstanding" with message transform method call failed at ../../../src/share/instrument/JPLISAgent.c line: 844

我的域名如下：

 class Product {
 String name
 String comments
 static hasMany = [components:Components]

 public asJSON(){
      println "product: "+this.id
    def builder = new groovy.json.JsonBuilder()
    def root = builder {
        id this.id
        name this.name
        comments this.comments
        components this.components.collect {it.asJSON()}

        }

    return builder.toString().replaceAll(/\\"/, '"').replaceAll(/\"\{/,'{').replaceAll(/\}\"/,'}')
 }
 }

组件：

class Components {
Product part_of
static hasMany = [alternatives:Alternatives]

public String asJSON(){
    def builder = new groovy.json.JsonBuilder()
    def root = builder {
        id this.id
        product (this.part_of)?this.part_of.asJSON():null
      //  alternatives (this.alternatives)?this.alternatives.collect {it.product.productAsJSON()} :null
    }

    return builder.toString()
}

}

当我执行以下操作时，我得到了异常

 Product.get(1).asJSON()

我已经检查过它没有递归调用自己。产品1有一个Component，它有一个名为part_of的Product实例，它是ID为5的产品

Grails中的Java ASSERTION错误
