I am looking for help on how to continue tracking this problem to its
source. A solution would be nice, but it is not expected.
I am using jdk1.5.0_01-x86_64 and have created a C++ library that
creates an embedded JVM. I want to use a bunch of Java that I have
written from within Octave (see www.octave.org for details). However,
when I compile my library into Octave and try start the JVM I get this
dump:
java.lang.InternalError
at java.util.zip.Inflater.init(Native Method)
at java.util.zip.Inflater.<init>(Inflater.java:79)
at java.util.zip.ZipFile.getInflater(ZipFile.java:373)

Since it works with a C++ main(), I am guessing that there is some
symbol in Octave that is clashing with what libzip.so would get from
else where. Using 'nm' I have not gotten too far. Anyone have any
suggestions on how to further isolate the cause of this error so that it
is not guess work. Oh, I have used gdb and strace with little success at
getting closer to the cause of the problem. Yeah, it was strace that
sent me looking at libzip.so:
stat("/usr/local/jdk1.5.0_01-x86_64/jre/lib/amd64/libzip.so",
{st_mode=S_IFREG|0755, st_size=112392, ...}) = 0
is right before the failure.
Any and all suggestions are appreciated. Thanks in advance...
