Bug 215

---- Reported by s_koehler 2006-04-09 11:32:14 ----

Hi,

in Issue 110 (https://jogl.dev.java.net/bugs/show_bug.cgi?id=110) i
sugguested, that people should be able to disable libloading. The goal was, to
be abled to provide an own way of library-loading - library loading without
using complicated ClassLoader techniques. 

Now, the number of libraries has been growing and the logic, when which library
is needed, are more complicated.

I have therefor decided to rewrite the NativeLibLoader so that it offers a
mechanism hook into the on-demand-loading of the libraries.

Important points concerning the rewrite:
- NativeLibLoader now consequently uses synchronized, no volatile things
(i don't think, that there is any noticable performance penality, since most of
loadXY()-methods are called only once during the live-time of the application)
- NativeLibLoader now offers a loadCGImpl()-method to replace the direct call to
System.loadLibrary("jogl_cg") within make/cg-common-CustomJavaCode.java
- A workaround for a JVM-Bug has been added, namely:
If you use bin\java.exe instead of jre\bin\java.exe to run a program with
System.loadLibrary("jawt"), then the JVM complaines about a missing awt.dll

Just another comment:

i used the line "Frame.getFrames();" to reference AWT, so that the awt.dll gets
loaded. If you know any better line, then use it. Another line that works is
"new Component() {};".

Incorporated and cleaned up Cg library loading -- thanks for the patch.
