protected Throwable (String message, Throwable cause, boolean enableSuppression, boolean writableStackTrace)

Constructs a new throwable with the specified detail message, cause, suppression enabled or disabled, and writable stack trace enabled or disabled. If suppression is disabled, getSuppressed for this object will return a zero-length array and calls to addSuppressed that would otherwise append an exception to the suppressed list will have no effect. If the writable stack trace is false, this constructor will not call fillInStackTrace(), a null will be written to the stackTrace field, and subsequent calls to fillInStackTrace and setStackTrace(StackTraceElement[]) will not set the stack trace. If the writable stack trace is false, getStackTrace will return a zero length array.

Note that the other constructors of Throwable treat suppression as being enabled and the stack trace as being writable. Subclasses of Throwable should document any conditions under which suppression is disabled and document conditions under which the stack trace is not writable. Disabling of suppression should only occur in exceptional circumstances where special requirements exist, such as a virtual machine reusing exception objects under low-memory situations. Circumstances where a given exception object is repeatedly caught and rethrown, such as to implement control flow between two sub-systems, is another situation where immutable throwable objects would be appropriate.

message    the detail message.
cause    the cause. (A null value is permitted, and indicates that the cause is nonexistent or unknown.)
enableSuppression    whether or not suppression is enabled or disabled
writableStackTrace    whether or not the stack trace should be writable
