[Bug java/18811] New: rhug build problem, regression?

[timo dot lindfors at iki dot fi]

I just noticed that building rhug from cvs fails with the current gcc from cvs.
I'm reporting this here because gcc 3.4.2 seems to build the problematic file so
this might be regression.

$ CVS_RSH=ssh cvs -d:pserver:anoncvs@sources.redhat.com:/cvs/rhug -z9 co rhug
$ cd rhug
$ export LD_LIBRARY_PATH=$INSTALLDIR/gcc/lib
$ PATH=$INSTALLDIR/gcc/bin:$PATH ./configure --prefix=$INSTALLDIR/rhug
$ PATH=$INSTALLDIR/gcc/bin:$PATH make
...
gcj --encoding=ISO-8859-1 -Wno-deprecated
--classpath=upstream/src:upstream:./upstream/src:./upstream -fassume-compiled -g
-O2 -c upstream/junit/tests/runner/AllTests.java -MT
upstream/junit/tests/runner/AllTests.lo -MD -MP -MF
.deps/upstream/junit/tests/runner/AllTests.TPlo  -fPIC -o
upstream/junit/tests/runner/.libs/AllTests.o
upstream/junit/tests/runner/AllTests.java:19: error: cannot find file for class
junit.runner.Sorter$Swapper
make[1]: *** [upstream/junit/tests/runner/AllTests.lo] Error 1
make[1]: Leaving directory `/home/lindi/src-2004-11-27/rhug/junit'
make: *** [all-recursive] Error 1


Next I managed to reproduce the issue with


[lindi@protu rhug]$ cd junit/
[lindi@protu junit]$ PATH=$INSTALLDIR/gcc/bin:$PATH gcj --encoding=ISO-8859-1
-Wno-deprecated --classpath=upstream/src:upstream:./upstream/src:./upstream
-fassume-compiled -g -O2 -c upstream/junit/tests/runner/AllTests.java -MT
upstream/junit/tests/runner/AllTests.lo -MD -MP -MF
.deps/upstream/junit/tests/runner/AllTests.TPlo  -fPIC -o
upstream/junit/tests/runner/.libs/AllTests.o
[lindi@protu junit]$ PATH=$INSTALLDIR/gcc/bin:$PATH gcj --version
gcj (GCC) 4.0.0 20041127 (experimental)
...

and noticed that the an older gcc handles the situation without errors


[lindi@protu junit]$ gcj --encoding=ISO-8859-1 -Wno-deprecated
--classpath=upstream/src:upstream:./upstream/src:./upstream -fassume-compiled -g
-O2 -c upstream/junit/tests/runner/AllTests.java -MT
upstream/junit/tests/runner/AllTests.lo -MD -MP -MF
.deps/upstream/junit/tests/runner/AllTests.TPlo  -fPIC -o
upstream/junit/tests/runner/.libs/AllTests.o
[lindi@protu junit]$ gcj --version
gcj (GCC) 3.4.2 20041017 (Red Hat 3.4.2-6.fc3)
...

Is this regression in gcc, a bug in rhug or something else?
