Re: Strange compilation errors on linux platform

Same identical issue, build works on windows, but fails with all sorts of strange compiler errors on RHEL6

Tried forcing encoding via <project.build.sourceEncoding>cp1252</project.build.sourceEncoding>

Tried via export JAVA_TOOL_OPTIONS=-Dfile.encoding=iso-8859-1

Same result, i guess u can fix it by not using gwt...

I am running into the same issue now. Any idea how to fix this?

We have a pretty heterogeneous team which works with GWT on Mac,
Windows & linux machines.
One of our latest commit crashed the automatic build which runs on
linux box.
The problem is that GWT java source generator fails with
NullPointerException at different places with the same configuration
inputs, therefore it is very hard to reproduce bug or nail it down.

The only regularity we've found is that it fails at some point when
trying to generate client bundles from PNG files.
Here are few examples:

We are using GWT 2.0.4  and tried to compile on
  a) fedora 13 x86_64  / Both sun Java 1.6.0_16 & java-1.6.0-
openjdk-1.6.0.0-42.b18.fc13.x86_64
  b) Ubuntu 10.04  x86 / Both sun Java 1.6.0_16 & OpenJDK Server VM
(16.0-b13) for linux-x86


I believe that problem is somewhere deep inside Java/GWT internals,
related to low level memory/threads handling because of following
  1) it compiles like a charm on Windows & Mac boxes
  2) it is not regular, i.e.  the same code fails at different places
during compilation


Is there anyone who have experienced something similar on linux? I
would really appreciate any help
