Thanks, but I am familiar with the command-line options for javac. I was
though under the impression that ToolProvider.getSystemJavaProvider()
returned a compiler which might not actually be "javac", and therefore one
could not just assume that the command-line options for "javac" would
necessarily be valid.
The problem with the getSystemJavaProvider is that it may well already
be loaded. It is too late for command line options. You need to exec
javac.exe the old way. See http://mindprod.com/jgloss/exec.html

I think that there is no need for "the old way" of executing Java
compiler nowadays.
The JavaCompiler instance created with getSystemJavaCompiler() allows
for specifying of the most of the command-line compiler's options using
either run(), or getTask() method (see Javadoc). AFAIK, the only
options not supported that way are non-standard options of the java
launcher called by javac (i.e. -J options), those memory related, and
the like... Those options must be specified for the JVM that runs
JavaCompiler tool.
