Looking at the source, the Compiler needs to be a:
org.apache.jasper.compiler.Compiler, which, clearly, javac is not.
So maybe I need to use the AntCompiler (I have no idea what this is
currently), and have it call javac.
This is all looking like it may not be worth it. Still, I may investigate
it further this weekend.

Looking at the code in org.apache.jasper.EmbeddedServletOptions, it appears
the parameter name should be "compilerClassName" rather than "compiler". If
compilerClassName is null, the following somewhat odd code in
org.apache.jasper.JspCompilationContext is executed:
if (options.getCompiler() == null) {
jspCompiler =
createCompiler("org.apache.jasper.compiler.JDTCompiler");
if (jspCompiler == null) {
jspCompiler =
createCompiler("org.apache.jasper.compiler.AntCompiler");
}
} else {
jspCompiler =
createCompiler("org.apache.jasper.compiler.AntCompiler");
if (jspCompiler == null) {
jspCompiler =
createCompiler("org.apache.jasper.compiler.JDTCompiler");
}
}
It appears the value of "compiler" is ignored, which explains why the JDT
compiler keeps getting used.
