gcj 3.4.3 with uClibc: deserialization issue

[yoann dot huiban at devoteam dot com]

Hello,

I built a gcj compilation toolchain for a MIPS embedded target (using
buildroot).
I only succeeded to build a gcj-3.4.3.

Then I compiled my jdk1.4 project into a single statically linked
executable.
The program runs on the target, but I encounter pbs during deserialization.
I get the following message:

0x3500D9:69346089:ERROR (datagrammanager:read): java.io.EOFException:
Attempt to read primitive data, but no data block is active.
<<No stacktrace available>>

This trace is generated in the readNextBlock method of the
java.io.ObjectInputStream class.

My mips executable communicates with another mips executable.
I also made a test building the same cross compilation toolchain, but for
x86.
The behaviour is exactly the same.

I read in the mailing list that there used to be deserialization issues in
the previous versions of gcj.
Is it possible/useful to update only the java/io/ObjectInputStream.java
file in gcj with a 4.x version ? (and then recompile, of course).



Thanks to all the people who contributed to this project!

Yoann
