jdeferthrow
The jdeferthrow package implements a trivial API for combining multiple
exceptions over a series of statements.
Usage
final var tracker = new ExceptionTracker<IOException>();
try {
doIO1();
} catch (IOException e1) {
tracker.addException(e1);
}
try {
doIO2();
} catch (IOException e2) {
tracker.addException(e2);
}
try {
doIO3();
} catch (IOException e3) {
tracker.addException(e3);
}
tracker.throwIfNecessary();
The above code will execute doIO1, doIO2, and doIO3, catching each
exception if any are raised. The throwIfNecessary method will throw
whichever of e1, e2, or e3 was caught first, with either of the other
two exceptions added to the thrown exception as a suppressed exception.
Concretely, if all of doIO1, doIO2, and doIO3 throw exceptions, the
throwIfNecessary method will throw e1 with e2 and e3 added to e1
as suppressed exceptions.
This effectively allows for accumulating exceptions over a range of statements and then throwing an exception at the end that contains all of the exceptions that were thrown.
If addException was not called, throwIfNecessary does nothing.

Development Snapshots
At the time of writing, the current unstable development version of the package is 1.4.0-SNAPSHOT.
Development snapshots may be available in the Central Portal Snapshots repository. Snapshots are published to this repository every time the project is built by the project's continuous integration system, but snapshots do expire after around ninety days and so may or may not be available depending on when a build of the package was last triggered.
