[Source] xj3d.nps branch build properties feedback: -Xlint:deprecated to -Xlint:deprecation

[Don Brutzman]

hi Terry, bravo on all of the Xj3D cleanups you have been continuing 
work on.

i got the following problem tonite, Netbeans 7.3 jdk 1.7.0_17

> compile.ogl:
> Compiling 2383 source files to C:\Xj3D.nps\classes
> javac: invalid flag: -Xlint:deprecated
> Usage: javac <options> <source files>
> use -help for a list of possible options
> C:\Xj3D.nps\build_nps.xml:185: Compile failed; see the compiler error output for details.
> BUILD FAILED (total time: 3 seconds)

build.properties showed
	javac.compilerargs=${javac.extdirs} -g -Xlint:unchecked -Xlint:deprecated

	javac -help
then
	javac -help -X
revealed
    [...]
 
-Xlint:{all,cast,classfile,deprecation,dep-ann,divzero,empty,fallthrough,finally,options,overrides,path,processing,rawtypes,serial,static,try,unchecked,varargs,-cast,-classfile,-deprecation,-dep-ann,-divzero,-empty,-fallthrough,-finally,-options,-overrides,-path,-processing,-rawtypes,-serial,-static,-try,-unchecked,-varargs,none} 
Enable or disable specific warnings

presumably jdk 7 is now stricter about settings and this revealed an 
incorrect setting which was overlooked earlier.

and so, changed spelling of -Xlint:deprecated to

	javac.compilerargs=${javac.extdirs} -g -Xlint:unchecked -Xlint:deprecation

and everything builds OK.  only 78 warnings now!  progress.  compilation 
seemed fast too, only 28 seconds following a clean.  8)

not sure if this change causes a problem with JDK 1.6, hopefully someone 
can confirm OK.

interestingly, adding flag -Xlint:all shows more warnings, some easy 
(such as duplicate casts).

the main branch compiles oK also (44 seconds).  don't think it uses the 
-Xlint settings at all, given repeated output messages of
> Note: Recompile with -Xlint:unchecked for details.

all the best, Don
