Running in valgrind does not help as there are many false positive.
As the crash seems to occur in JVM generated code, I think we need a
java call stack to be able to see what's wrong.
The thread crashing seems to be a java thread (there is only JVM +
pthread in the stacktrace).

In a sbuild inside a VM without X, I don't reproduce the issue. I have
interrupted the build just after the "Building documentation" for en_US
step to drop a bash shell, I ran the documentation build in a loop.
But I didn't got any crash.

I saw that there is a bugfix release 6.0.2 with many fixes [0].

As no one seems to be able to reproduce the issue, I suggest to:
 - Try to reproduce on the x86-bm-01 machine and retrieve a core dump
   to dump other thread and run jstack to get the java stacktrace and
   see what's wrong
 - Try to build the 6.0.1 version and also the new 6.0.2 version
   on x86-bm-01 to ensure that the crash is still reproducible with
   6.0.1 and if it is fixed with 6.0.2.

I didn't find any possible fixed issue in the list of fixed bugs in
6.0.2 that could match our crash without entering in each of them.

=> So, can anyone access the x86-bm-01 machine to try to reproduce and
get a core dump of this crash ?
