poll(...) gets "Interrupted system call" on jni

For a little variety in my life, I run into a problem with GCJ on linux.
I use a --disable-shared GCJ, built yesterday evening (revision 117030)...
I have a java application that calls a native lib over JNI. This lib
performs a poll() on a network socket in a loop. This all works flawless
when running with a sun jdk. As soon as I compile the application with
GCJ, the poll() sometimes fail and sets errno to 4 (Interrupted system
Google told me that this can (respectively should) be ignored and
indeed, everything works if I just continue in the loop. But I'm a
little confused why this only happens when the application is compiled
What makes me think that GCJ might do something bad is, that the lib is
a widely used java library. So I guess no one run into this bug with a
"normal" JRE so far...
I'm not entirely sure if it's a GCJ problem. Actually I don't even know
what "Interrupted system call" means exactly (I guess the poll was
simply interupted). Any commends welcome...
