// 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.
