Revision 121290 is OK:

http://gcc.gnu.org/ml/gcc-testresults/2007-01/msg01092.html

This patch

http://gcc.gnu.org/ml/java-patches/2007-q1/msg00217.html

may be the cause.
Comment 1 H.J. Lu 2007-01-29 20:08:52 UTC 
Oops. I meant to say this patch

http://gcc.gnu.org/ml/java-patches/2007-q1/msg00237.html

might be the cause.
Comment 2 Tom Tromey 2007-01-29 20:16:55 UTC 
This is very weird.  I don't see how it can happen...

The definition is:

static jvmtiError JNICALL
_Jv_JVMTI_SuspendThread (MAYBE_UNUSED jvmtiEnv *env, jthread thread)

and afaics jthread is defined in include/jvmti_md.h:

typedef java::lang::Thread *jthread;

Hmm... perhaps this compilation is picking up some *other* jvmti.h?
One that defines jthread as 'jobject'?  Perhaps -E or the .d file would
help here.
Comment 3 H.J. Lu 2007-01-29 21:00:33 UTC 
I do have an older gcc 4.3 installed and I am doing "make -j8" on an
ia64 machine with 16 pocessors. Is libjava parallel build safe?
Comment 4 Tom Tromey 2007-01-30 19:47:55 UTC 
Yes, as far as we know libjava is parallel build safe.
Could you paste the command line for the failing compilation?
And also run it with -E and see what jvmti*.h files are
actually being used?
Perhaps we have a wrong -I or something like that.
Comment 5 H.J. Lu 2007-07-13 13:26:22 UTC 
Seems to work now.
