Right, the JSP container checks for javax.tools.ToolProvider and uses
its presence as an indication of a JDK 1.6 runtime, which triggers
in-memory compilations of JSPs.
When I disassemle javax.tools.ToolProvider from 1.6.0-beta2, I get this:
javap -public javax/tools/ToolProvider
Compiled from "ToolProvider.java"
public class javax.tools.ToolProvider extends java.lang.Object{
public static javax.tools.JavaCompilerTool
getSystemJavaCompilerTool();
public static java.lang.ClassLoader getSystemToolClassLoader();
}
whereas when I disassemble the version of this class in the latest 1.6
release
candidate, I get:
javap -public javax/tools/ToolProvider
Compiled from "ToolProvider.java"
public class javax.tools.ToolProvider extends java.lang.Object{
public static javax.tools.JavaCompiler getSystemJavaCompiler();
public static java.lang.ClassLoader getSystemToolClassLoader();
}
As you can see, getSystemJavaCompilerTool() has been renamed to
getSystemJavaCompiler(), and javax.tools.JavaCompilerTool has been
changed to javax.tools.JavaCompiler.
Obviously, the version of
org.apache.jasper.compiler.Jsr199JavaCompiler that's bundled in
GlassFish v2 b24's appserv-rt.jar uses the newer symbols.
We'll have to change, recompile, and rebundle this class to make it
compatible
with 1.6.0-beta2 for the time being, until a newer JDK 1.6 beta has been
released. This should happen in time for b25, so stay tuned.
Thanks,
Jan
