Field Details

commonElementCount

final int commonElementCount

Number of stack trace elements shared with the parent Throwable's stack

stackLength

final int stackLength

Number of stack trace elements exclusive to this Throwable, i.e., not in common with the parent Throwable's stack

stackTrace

final StackTraceElement[] stackTrace

The stack trace of this Throwable. This needs to be captured separately since Throwable.getStackTrace() can change.

suppressed

final Throwable[] suppressed

The suppressed exceptions attached to this Throwable. This needs to be captured separately since Throwable.getSuppressed() can change.
