Thanks for reporting this. I added your information here for the record.

Reading your exception, I am surprised that your programs tries to find the native in the directory "/opt/astropixelprocessor/natives" which seams unusual or manually defined. When reading the getTempDir function it seams the default temporary dir may overriden by one of the following
- -Djava.io.tmpdir=/my/own/path
- Environment variable "TEMP"
- Environment variable "TMPDIR"

The failing line is here. Two ways to know a little more about this
- Place a breakpoint there to understand what will be the flow on your computer.
- Get debugging information in console by adding the VM argument -Djogamp.debug.IOUtil

The second option lead to this kind of output on my computer

IOUtil.getTempRoot(): tempX1 </var/folders/d2/85g_sxm91rg71yyky4gg6l6h0000gn/T>, used true
IOUtil.getTempRoot(): tempX3 </var/folders/d2/85g_sxm91rg71yyky4gg6l6h0000gn/T>, used false
IOUtil.getTempRoot(): tempX4 </Users/martin>, used true
IOUtil.getTempRoot(): tempX2 <null>, used false
IOUtil.testDirImpl(tempX1): </var/folders/d2/85g_sxm91rg71yyky4gg6l6h0000gn/T>, create true, exec false: true
IOUtil.testDirImpl(tempX1): </var/folders/d2/85g_sxm91rg71yyky4gg6l6h0000gn/T/jogamp_0000>, create true, exec false: true
IOUtil.getTempRoot(): temp dirs: exec: /var/folders/d2/85g_sxm91rg71yyky4gg6l6h0000gn/T/jogamp_0000, noexec: /var/folders/d2/85g_sxm91rg71yyky4gg6l6h0000gn/T/jogamp_0000
IOUtil.testDirImpl(testDir): </var/folders/d2/85g_sxm91rg71yyky4gg6l6h0000gn/T/jogamp_0000/file_cache>, create true, exec false: true


Then I can verify where the native was unpacked by calling

tree /var/folders/d2/85g_sxm91rg71yyky4gg6l6h0000gn/T/jogamp_0000/file_cache

Which yield to

/var/folders/d2/85g_sxm91rg71yyky4gg6l6h0000gn/T/jogamp_0000/file_cache
