Project loom now have JFR events, but our parser currently do not support some of the changes made. One change is that the thread type now have a boolean isVirtual field.

 <Type name="Thread" label="Thread">
    <Field type="string" name="osName" label="OS Thread Name" />
    <Field type="long" name="osThreadId" label="OS Thread Id" />
    <Field type="string" name="javaName" label="Java Thread Name" />
    <Field type="long" name="javaThreadId" label="Java Thread Id" />
    <Field type="ThreadGroup" name="group" label="Java Thread Group" />
    <Field type="boolean" name="isVirtual" label="Virtual Thread" />
  </Type>

We must ensure that we can parse recordings produced by project Loom.
