This implementation returns the cause that was supplied via one of the constructors requiring a Throwable, or that was set after creation with the CompilerException.initCause(Throwable) method. While it is typically unnecessary to override this method, a subclass can override it to return a cause set by some other means. This is appropriate for a "legacy chained throwable" that predates the addition of chained exceptions to Throwable. Note that it is not necessary to override any of the PrintStackTrace methods, all of which invoke the getCause method to determine the cause of a throwable. the cause of this throwable or null if the cause is nonexistent orunknown.

This method can be called at most once. It is generally called from within the constructor, or immediately after creating the throwable. If this throwable was created with CompilerException.CompilerException(String,Throwable) , this method cannot be called even once.
Parameters:
  cause - the cause (which is saved for later retrieval by the CompilerException.getCause()method). (A null value is permitted, and indicates that the cause isnonexistent or unknown.) a reference to this Throwable instance.
throws:
  IllegalArgumentException - if cause is this throwable. (A throwablecannot be its own cause.)
throws:
  IllegalStateException - if this throwable was created with CompilerException.CompilerException(String,Throwable), or this method has already been called on thisthrowable.
