Example 3 with JCImageThread

use of com.ibm.dtfj.image.javacore.JCImageThread in project openj9 by eclipse.

/**

 * <b>For internal building purposes only</b>. Do not call outside the DTFJ implementation.
 * <br><br>
 * In most cases, the threadID is the tid in a javacore, but in some other occasions, the id
 * passed could be the system_thread_id or even the native thread. If a java thread is not
 * found via tid, see if it can be found indirectly by an image thread that may be associated
 * with the java thread (the image thread has a system thread ID as well as a native thread ID).
 * @param threadID usually, tid in a javacore, may be id of some other internal vm datastructure.
 * @return found java thread or null.
