#941 Jikes fails to compile without any error message

[Eric L.]

Hi,

I tried to compile freemind 0.8.0 with kaffe 1.1.6,
i.e. with jikes, and the
compilation stops at some point without any
error message, so that I'm stuck to
find the reason for the error.

I tried further to call directly jikes, with strace on
top of it. To be honest, the only thing I get from it
is that it's a segmentation fault.
I also tentatively tried:
- 'strace -v' but it didn't give any more information
- and bump target/source to 1.4, but it didn't
make any difference.

I attach the end of the ant output (-verbose file),
as well as the strace output (-strace) to this bug,
and you can grab a copy of the
development tree from
http://eric.lavar.de/freemind.free3.tgz. Each
output files contains the command(s) called at
the beginning of the file.

Thanks for your help,
Eric

strace isn't much use, can you get a backtrace instead? Or
provide complete recreate directions?

Hi,

I tried to debug Jikes with gdb, and got the following result:

[read
/usr/share/java/batik-all.jar/org/apache/batik/transcoder(Transcoder.class)]

Program received signal SIGSEGV, Segmentation fault.

So, I understand as much as that the Length function is
called on a null pointer, but there I fail to get a grasp on
the code.

Hi again,

how to reproduce:
1. download and unpack the file
http://eric.lavar.de/freemind.free3.tgz.
2. building FreeMind will create a 'bin' at the same level
as the freemind directory, so make sure you have no
directory of the same name.
3. call the 2nd 'ant' command at the beginning of
freemind.free3-verbose.txt (the first one is to clean).
4. then you can call the jikes command out of
freemind.free3-strace.txt as often as you want to reproduce
the issue (that's what I did with strace and gdb).

The build dependencies are, beside ant and jikes:
librelaxng-datatype-java, libjaxp1.2-java,
libcommons-lang-java, libbatik-java (>= 1.6), rhino,
libxerces2-java, libforms-java, libcommons-codec-java
(it's of course easier if you have Debian Unstable lying
somewhere around).

Thanks, Eric
