I've filed PR45773 concerning the new regression in gcj where java classes can
no longer be compiled with ecj.jar. Since r163770 (with r163814 backported to fix
the libjava build), any attempt to compile a java source file with gcj produces
the error...
gcj --main=testme -O testme.java
Exception in thread "main" java.lang.NoClassDefFoundError: org.eclipse.jdt.internal.compiler.batch.GCCMain
at gnu.java.lang.MainThread.run(libgcj.12.dylib)
Caused by: java.lang.ClassNotFoundException: org.eclipse.jdt.internal.compiler.batch.GCCMain not found in gnu.gcj.runtime.SystemClassLoader{urls=[file:/sw/share/java/ecj/ecj.jar,file:./], parent=gnu.gcj.runtime.ExtensionClassLoader{urls=[], parent=null}}

This problem does not exist at r163768. I am reposting this problem since the new
bugzilla keeps reporting...
GCC Bugzilla has suffered an internal error. Please save this page and send it to dberlin@gcc.gnu.org with details of what you were doing at the time this message appeared.

There was an error sending mail from '"howarth at nitro dot med.uc.edu" <gcc-bugzilla@gcc.gnu.org>' to 'java-prs@gcc.gnu.org':Can't send data
whenever I add new information and nothing appears in the gcc-bugs archives from those sessions
(although the PR itself if updated).

With a simple HelloWorld class:
$ cat HelloWorld.java
public class HelloWorld
{
public static void main(String[] args) { System.out.println("Hello World!"); }
}
current HEAD works fine for me:
$ /home/andrew/build/gcj/bin/gcj --main=HelloWorld -O HelloWorld.java
$ LD_LIBRARY_PATH=/home/andrew/build/gcj/lib64 ./a.out
Hello World!
$ /home/andrew/build/gcj/bin/gcj --version
gcj (GCC) 4.6.0 20100928 (experimental) [trunk revision 164689]
Can you attach the testme.java file?

Of course it does because the bug was just fixed...
