Trying to understand why LO seems freezed for some seconds when a module is started

Hello,
On master branch (not on 3.5 branch), each time I start a module Calc,
Writer or Impress (I didn't test on others), when I begin to type something,
it seems to freeze for some seconds (about 10 secs) then everything seems
ok.
So I runned valgrind by using this :
valgrind --tool=memcheck --num-callers=50 --trace-children=yes ./soffice.bin
2>&1 | tee /tmp/valgrind.log
With this, I can't start LO at all because there are too much errors. By
taking a look, 98% of them are like this :

So I took a look at jvmfwk/plugins/sunmajor/pluginlib/sunjavaplugin.cxx but
that's far beyond my feeble C++ skills to understand what could be the
problem.
Now perhaps someone may have an idea.
I noticed these lines too :
700 #ifdef MACOSX
701 vm_args.version= JNI_VERSION_1_4; // issue 88987
702 #else
703 vm_args.version= JNI_VERSION_1_2;
704 #endif
If we support jdk 1.4 min, we could use JNI version 1.4 according to this
http://docs.oracle.com/javase/1.4.2/docs/guide/jni/jni-14.html, no ? (or
perhaps it would need lots of changes to use it except for MacOS where it's
already used)
Julien.
