Public bug reported:

im programing a simple app which uses many threads and mysql connection
the jvm crashes in a few minutes after the threads are continuously created.
i suspect it has something to do with the way linux manages threads (NPTL)
i use a static threadlocal instance,which initializes a mysql connection

i've encountered this on different hardware :
intel e6850 , 6gb ram 
hp probook 4520s core i3 350m, 4gb ram

i've tried to find a fix via google for many hours but found nothing useful or remotely helpful
the same app runs flawlessly on windows 7 x64 jdk from sun,i've also tried the jdk from sun on linux,but the same problem arises

is there any way to choose something different than NPTL ?
