To suspend an executing thread:
The thread suspends its execution. The current call stack for the thread is displayed, and the current line of execution is highlighted in the editor in the Debug Perspective.
When a thread suspends, the top stack frame of the thread is automatically selected.� The Variables View shows the stack frame's variables and their values.� Complex variables can be further examined by expanding them to show the values of their members.
When a thread is suspended and the cursor is hovered over a variable in the Java editor, the value of that variable is displayed.
