Hi Andrew: A build of the test_noninteractive target generates the following java warnings
cd /home/software/plplot/HEAD/build_dir/examples/java && /usr/bin/javac
-classpath /home/software/plplot/HEAD/build_dir/bindings/java -d
/home/software/plplot/HEAD/build_dir/examples/java -encoding UTF-8
/home/software/plplot/HEAD/plplot.git/examples/java/x20.java
/home/software/plplot/HEAD/plplot.git/examples/java/x20.java:328: warning:
Resource leak: 'in' is never closed
in = new BufferedReader( new FileReader( fname ) );
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
/home/software/plplot/HEAD/plplot.git/examples/java/x20.java:329: warning:
Resource leak: 'in2' is never closed
in2 = new DataInputStream( new DataInputStream( new
BufferedInputStream( new FileInputStream( fname ) ) ) );
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
2 problems (2 warnings)
Those are the only java warnings I get so we are in pretty good shape
with regard to the Java examples, but it would be nice to get rid of
these warnings completely.
For my Debian stable platform, javac refers to a gcj wrapper, i.e.,
software@raven> ls -l /etc/alternatives/javac
lrwxrwxrwx 1 root root 24 Oct 4 12:56 /etc/alternatives/javac ->
/usr/bin/gcj-wrapper-4.9*
You can also generate these specific java example 20 warnings with the
following much simpler
test:
software@raven> make VERBOSE=1 x20j >| x20j.out 2>&1
I have attached a compressed version of x20j.out to give you full
context.
Would you be willing to take a look at this?
