-@node Java Exceptions
-@section Java Exceptions
-
-The Java language uses a slightly different exception handling model
-from C++. Normally, GNU C++ automatically detects when you are
-writing C++ code that uses Java exceptions, and handle them
-appropriately. However, if C++ code only needs to execute destructors
-when Java exceptions are thrown through it, GCC guesses incorrectly.
-Sample problematic code is:
-
-@smallexample
- struct S @{ ~S(); @};
- extern void bar(); // @r{is written in Java, and may throw exceptions}
- void foo()
- @{
- S s;
- bar();
- @}
-@end smallexample
-
-@noindent
-The usual effect of an incorrect guess is a link failure, complaining of
-a missing routine called @samp{__gxx_personality_v0}.
-
-You can inform the compiler that Java exceptions are to be used in a
-translation unit, irrespective of what it might think, by writing
-@samp{@w{#pragma GCC java_exceptions}} at the head of the file. This
-@samp{#pragma} must appear before any functions that throw or catch
-exceptions, or run destructors when exceptions are thrown through them.
-
-You cannot mix Java and C++ exceptions in the same translation unit. It
-is believed to be safe to throw a C++ exception from one file through
-another file compiled for the Java exception model, or vice versa, but
-there may be bugs in this area.
