Hi Gerlando,
I think you probably used the tracing RCP from my repository, that
I forgot to update to Trace Compass, it was still using the code
from Linux Tools. I just changed it to Trace Compass
http://secretaire.dorsal.polymtl.ca/~gbastien/TracingRCP/TraceCompass/
We are in the process of setting official daily builds of Trace
Compass on the Eclipse website, so my repository will become an
unofficial mirror. Where did you get the link to download the
build you used? Just so we know where to update it.
Thanks,
Geneviève

Hi,
I'm trying to use the Linux Tools Trace Viewer (i.e. Trace Compass
outside of Eclipse, if I understand it correctly) to read some
traces created by LTTNG on a MIPS (big endian) architecture.
However, upon clicking on the trace file in order to show it, I
get this message:
Exception in thread "Thread-35" java.lang.NullPointerException

The same test run on an ARM (little endian) platform seems to work
fine though. As I remember there've been endianness issues in the
past, and I assume most tests are run on x86 platform (hence
little endian), could it be possible that we're hitting the same
issue again?
Please find attached a test case where I could get the above
error.
If it makes any difference, the daily build I used is
linuxtools-trace-viewer-1.1.0-20141203-0203-linux.gtk.x86_64.tar.gz.
Could anyone please help me with this issue?
Thank you!
Gerlando
