[Bug 166] New: System.loadLibrary: look in platform default library paths

http://sablevm.org/bugs/show_bug.cgi?id=166

           Summary: System.loadLibrary: look in platform default library
                    paths
           Product: SableVM
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: default
        AssignedTo: [email protected]
        ReportedBy: [email protected]

It would be nice if, to be compatible with some other JVMs like gij and Sun JDK,
System.loadLibrary could automatically look in /lib and /usr/lib (or /lib64 and
/usr/lib64 as appropriate) if it doesn't find the library in the locations
listed in the relevant system properties.

Here is a test program (which obviously assumes that the named library exists in
a standard directory!)

public class TestLib {

  public static void main (String args []) {
    System.out.println ("java.library.path = " + System.getProperty
("java.library.path"));
    System.out.println ("gnu.classpath.boot.library.path = " +
System.getProperty ("gnu.classpath.boot.library.path"));
    System.loadLibrary ("swt-pi-gtk-3139");
  }

}

Output when run on sablevm SDK 1.13:

java.library.path = .
gnu.classpath.boot.library.path = /usr/local/lib/sablevm-classpath
java.lang.UnsatisfiedLinkError: Native library `swt-pi-gtk-3139' not found (as
file `libswt-pi-gtk-3139') in gnu.classpath.boot.library.path and java.library.path
