<AWT Dev> Bug 6913179, FileDialog uses native GTK under Linux: first patch

[Damjan Jovanovic]

On my setup, with your patches, FileDialogTest.java fails to even start:

$ java sun/awt/X11/FileDialogTest
Exception in thread "main" java.lang.InternalError: Unable to load
native GTK libraries
	at com.sun.java.swing.plaf.gtk.GTKLookAndFeel.initialize(GTKLookAndFeel.java:1447)
	at javax.swing.UIManager.setLookAndFeel(UIManager.java:531)
	at javax.swing.UIManager.setLookAndFeel(UIManager.java:576)
	at sun.awt.X11.FileDialogTest.main(FileDialogTest.java:146)

But then jconsole does the same.

Turns out your patches introduce a regression that totally breaks the
GTK LAF for me, since they look for the wrong gthread library name,
causing GTK to fail to load:

+#define GTHREAD_LIB "libgthread-2.0.so"

$ ls /usr/lib/libgthread*
/usr/lib/libgthread-2.0.so.0  /usr/lib/libgthread-2.0.so.0.2200.2

Note the ".0" at the end.

$ strace -f java sun/awt/X11/FileDialogTest
...
[pid   449] open("/lib/tls/i686/cmov/libgthread-2.0.so", O_RDONLY) =
-1 ENOENT (No such file or directory)
[pid   449] open("/lib/tls/i686/libgthread-2.0.so", O_RDONLY) = -1
ENOENT (No such file or directory)
[pid   449] open("/lib/tls/libgthread-2.0.so", O_RDONLY) = -1 ENOENT
(No such file or directory)
[pid   449] open("/lib/i686/cmov/libgthread-2.0.so", O_RDONLY) = -1
ENOENT (No such file or directory)
[pid   449] open("/lib/i686/libgthread-2.0.so", O_RDONLY) = -1 ENOENT
(No such file or directory)
[pid   449] open("/lib/libgthread-2.0.so", O_RDONLY) = -1 ENOENT (No
such file or directory)
[pid   449] open("/usr/lib/tls/libgthread-2.0.so", O_RDONLY) = -1
ENOENT (No such file or directory)
[pid   449] open("/usr/lib/i686/cmov/libgthread-2.0.so", O_RDONLY) =
-1 ENOENT (No such file or directory)
[pid   449] open("/usr/lib/i686/libgthread-2.0.so", O_RDONLY) = -1
ENOENT (No such file or directory)
[pid   449] open("/usr/lib/libgthread-2.0.so", O_RDONLY) = -1 ENOENT
(No such file or directory)
[pid   449] open("/usr/lib/i486-linux-gnu/libgthread-2.0.so",
O_RDONLY) = -1 ENOENT (No such file or directory)
...

This is with the 32 bit Linux Mint 8, but Ubuntu 9.04 has the same problem:

$ ls /usr/lib/libgthread*
libgthread-2.0.so.0         libgthread-2.0.so.0.2000.1

So I don't know where you're testing, that the GTK LAF hasn't regressed.

Otherwise I will test more later.

Thank you for the great work
