// Check that NullPointerExceptions thrown from library code are

// caught.  This detects a number of failures that can be caused by

// libgcj being built incorrectly.  In particular, we ensure that a

// SEGV in native (i.e. C++) code in libgcj is handled correctly.

// Regrettably, we cannot guarantee that Double.parseDouble() will

// always be native code, or that it will never be inlined.  It could

// be argued that we should add a method to libgcj that will be

// guaranteed forever to be native, but I'm reluctant to add to the

// library for the sole purpose of performing this test.
