Re: [JVM-B] The best way to use a JVMBridge-based module.

[Artem Gr <ar...@bi...>]

I've discovered "the hard way" that JVM-Bridge is unstable under a 
modern kernel-level threading library.
Fortunately, this is a known problem, one of my own C++ programs is 
unstable in a similar way too, so i knew about the "libmap.conf" trick, 
and indeed, it works.
My JDBC program - "convertor" - keeps failing with mysterious Java 
errors, like NullPointerException and OutOfMemory, until i add

[convertor]
libthr.so.2             libc_r.so.6


to /etc/libmap.conf (this is on FreeBSD). Then everything runs smooth.

I suspect the same problem might arise under NPTL.
