--------------------------------------------------------------

I think, I can reproduce this, and I found the root cause. It is related to the issue mentioned at http://lists.gnu.org/archive/html/autoconf/2011-10/msg00000.html and I eventually came up with the reason because after checking the usual suspects like {{CLASSPATH}} and the like I finally wondered whether it might have something to do with the fact that Java emits english error messages during configure, but german messages otherwise.

In short, the JVM fails to locate the *.class file within an path that contains (e.g.) Umlauts, such as in {{~/Arbeitsfläche/Thrift}} because of {{LC_ALL=C}} being set by configure. The symptom is, that 

{code}
java configtest_ax_javac_and_java
{code}

works fine when invoked by hand, but configure fails at exactly that step, even with an explictly set classpath {{-cp .}} with the message:

{code:title=config.log}
Running "/usr/bin/javac configtest_ax_javac_and_java.java"
Running "/usr/bin/java configtest_ax_javac_and_java"
Error: Could not find or load main class configtest_ax_javac_and_java
{code}

Temporarily adding {{LC_ALL=}} right before the Java check solves the issue. The other workaround is to use a path using only {{LC_ALL=C}}-compatible characters.

*Question*: 
Is there something we could/should change in the config scripts to avoid this annoying issue? It is quite hard to track down and it cost me at least two hours to find it.
