Package: gcj-3.0
Version: 1:3.0.4-6
Severity: normal
Hi. I have the following piece of code that compiles correctly but then
gives an error when run. It involves calling a default constructor for
an inner class.
If gcj won't accept this default constructor, it should give a compile
error. If gcj will accept this default constructor, it should run
without errors.
Currently it compiles cleanly but produces broken bytecode; you don't
have a clue that anything's wrong until you happen to run that
particular piece of code. This can be quite a problem in a large
project where it becomes difficult to test the execution of every possible
path through the software for compile breakages.
public class Test {
public static void main(String[] args) {
new Test().sayHi();
}
public void sayHi() {
new Foo().sayHi();
}
private class Foo {
public void sayHi() {
System.out.println("Hi");
}
}
}

Hi

Exception in thread "main" java.lang.VerifyError: (class: Test$Foo,

Thanks - Ben.

Changes:
gcc-3.0 (1:3.0.4ds3-14) unstable; urgency=low
.
* Build libstdc++ runtime only (on HPPA build gcc-3.0 as well as the
default compiler).
Note: The libstdc++ runtime does not build on a glibc-2.3.1 based
system!
* Add SH support.
* Backport patch from HEAD to build with bison > 1.35.
* Install gcj-wrapper (closes: #143912, #156792, #173290). Well this
doesn't help much as we don't build gcj-3.0 anymore ...
* Install fixed gij-wrapper (closes: #167569). Doesn't help anymore.
* Closing reports for the packages that are not built anymore from
this source package and are fixed in a newer version (gcc-3.2.x),
which becomes the default version now:

+ gij: better error reporting on `class not found' (closes: #125649).
+ Lockup during .java->.class compilation (closes: #141899).
+ Compile breaks using temporary inner class instance (closes: #141900).
+ Default constructor for inner class causes broken bytecode.
(closes: #141902).
+ gij-3.2 linked against libgcc1 (closes: #165180).
+ gij-wrapper understands -classpath parameter (closes: #146634).
