A ThdlLazyException wraps a "real" java.lang.Exception. ThdlLazyException, however, is unchecked. Thus, if you want to be a lazy Java programmer, you can use this idiom:
// Note that bleh does not throw any checked exceptions: public static void bleh() { try { Foo.bar(); } catch (Throwable t) { // Nah, this'll never happen! throw new ThdlLazyException(e); } }
Now your code appears to be well written, and no one but the user will ever know the difference.
In Java 1.4 (1.3?), Sun introduced constructors for java.lang.Error that allow much the same thing. This code is Java 1 compatible, though, and is also a red flag, equivalent to a // FIXME comment.
