The obvious difference is that Tomcat 6 compilation targets Java 5
whereas Tomcat 7 targets Java 6. For a simple test JSP:
Tomcat 6 (1.5) - 3,488
Tomcat 7 (1.5) - 3,530 +1%
Tomcat 7 (1.6) - 3,668 +6%
The 1% will be a combination of:
- Tomcat 7 uses version 3.6 of the Eclipse compiler while Tomcat 6 uses
3.3.1.
- the source code differences you can see in the .java files.
Hmm....
I tried forcing 1.5 as the source/target version for JspC -- I'm still
over 65K with Tomcat 7.
I wonder if there's enough extra hidden code generated by use of
generics...
Anyway, I guess the page owners will have to try to clean things up.
Is it possible that the source/target version is being ignored, e.g. for
the Ant task form of JspC?
I ask as javac fails to compile the Java code generated by jasper as
well for the same reason -- the _jspService method is too big. When I
force 1.5 as the target and source version, however, javac compiles the
generated Java code just fine.
When I try the same trick with my precompilation Ant script, however, ala
<jasper2 uriroot="${docBaseLocation}"
classpath="${wcWebAppClasspathAsString}"
compile="true" outputDir="${outputDir}"
classDebugInfo="true" smapSuppressed="${smapSuppressed}"
compilerSourceVM="1.5" compilerTargetVM="1.5"
validateXml="false" listErrors="true"
verbose="${jspcVerbosityLevel}" jspFiles="${jspFileList}"/>
I still get the same failure, which seems rather odd. You'd think that
JDT/EJC can't be generating that much larger code than javac.
