From: "vnasardinov at gmail dot com" <gcc-bugzilla@gcc.gnu.org> To: java-prs@gcc.gnu.org Subject: [Bug libgcj/27101] New: GCJ rejects valid code (for Sun's measure of "valid') Date: Mon, 10 Apr 2006 13:55:00 -0000 [thread overview] Message-ID: <bug-27101-8557@http.gcc.gnu.org/bugzilla/> (raw) [-- Warning: decoded text below may be mangled, UTF-8 assumed --] [-- Attachment #1: Type: text/plain, Size: 3053 bytes --] This is probably a duplicate of something that has been filed before, but my cursory search failed to turn up any similar tickets. GCJ rejects code that both Sun and Eclipse compilers accept. Here's the test case: | $ cat Reluctant.java | public class Reluctant { | private Reluctant internalInstance = new Reluctant(); | | public Reluctant() throws Exception { | throw new Exception("I'm not coming out"); | } | | public static void main(String[] args) { | try { | Reluctant b = new Reluctant(); | System.out.println("Surprise!"); | } catch (Exception ex) { | System.out.println("I told you so"); | } | } | } The test comes from http://www.javapuzzlers.com/java-puzzlers.zip Here's what I'm using | $ gcj -v | Using built-in specs. | Reading specs from /usr/lib/gcc/x86_64-redhat-linux/4.1.0/libgcj.spec | rename spec lib to liborig | Target: x86_64-redhat-linux | Configured with: ../configure --prefix=/usr --mandir=/usr/share/man \ | --infodir=/usr/share/info --enable-shared --enable-threads=posix \ | --enable-checking=release --with-system-zlib --enable-__cxa_atexit \ | --disable-libunwind-exceptions --enable-libgcj-multifile \ | --enable-languages=c,c++,objc,obj-c++,java,fortran,ada \ | --enable-java-awt=gtk --disable-dssi \ | --with-java-home=/usr/lib/jvm/java-1.4.2-gcj-1.4.2.0/jre \ | --with-cpu=generic --host=x86_64-redhat-linux | | Thread model: posix | gcc version 4.1.0 20060304 (Red Hat 4.1.0-3) Here's the compilation error the above code triggers: | $ gcj -C Reluctant.java | Reluctant.java: In class 'Reluctant': | Reluctant.java: In method 'finit$()': | Reluctant.java:2: error: Exception ^[$-1òøjava.lang.Exceptionòù can't be thrown in initializer. | private Reluctant internalInstance = new Reluctant(); | ^ | 1 error Here's what the Eclipse compiler has to say: | $ ecj -v | Eclipse Java Compiler v_585_R31x, 3.1.2 release, Copyright IBM Corp 2000, 2006.
