Changed Javac Compiler API

[billfen]

Dave,

Thanks for checking - I'm glad to hear that users of JDK 6-27 can
successfully compile.  That makes removing the internal compiler API less
urgent.  (But still necessary - it could break at any time.)

I'm not sure what the plugin is doing wrong - will be fun to find out.  It
just passes parameters to NetRexx.

Thanks again.

Bill,

on my Windows 7 VM, I am running with Java 7 - I did not see any strangeness, but will check tomorrow with all the NetRexxA examples I can find.

best regards,

René.

Very strange - on my system it seems to be related to using the jre
contained within the jdk as opposed to using the normal jre, but I just
discovered that seconds ago.

Thanks for checking Java 7 - hopefully that means the internal API will
work for a while.  I suspect at some point Oracle will try to purge every
instance of "sun" that it can find :)

Since I come from New England, "Light dawns on Marblehead...".  I was wrong
about the API changing - sorry about the confusion.

I forgot that I had included a copy of tools.jar in my jre\lib\ext
directory a long time ago, and I didn't realize it was being used.  I got
rid of it and changed the plugin code to properly find and use the one in
the JDK.    

I still think adopting the public API rather than using the internal API is
a good idea (eventually).  The ability to use different Java compilers
would be nice as well.

Bill

It definittely depends that you need to have

tools.jar
in ...\java\JDK1.7xx\jre\lib\

*and*

NetRexC.jar

in ...\java\JDK1.7xx\jre\lib\ext\

(at least, when you want to avoid ANY CLASSPATH changes, which are NOT
honoured by JEDIT, for instance)

Hi Bill -

You may have just solved a big problem for NetRexx!

I have been wondering how to pursue support for the Java Compiler API,
because I know we need it for JSR223 and other IDE uses so that we can
do complete compile and execution of NetRexx code in memory without file
IO. But the ARB decided that NetRexx 3.01 would support Java 1.5 (that
may be reasonable - I have no idea how widespread it's use is) which
does not have the Java Compiler API. That limited us to passing NetRexx
code to the translator in memory strings but still needing to pass the
output Java code in files to the Java compiler. It also limited us to
Java compilers that provide the unofficial com.sun.tools.javac.Main
compiler interface (Oracle/Open JDK/Jikes/?). That interface is not
likely to go away as all IDE tools like Ant and Eclipse used it, not
just NetRexx, since it was the only reasonable performance option prior
to the Java 1.6 Compiler API (aka JSR199).

But I think that if we can detect the version of JDK or more
specifically, the presence of the Compiler API, we can still support
Java 1.5 while offering advanced compile options to Java 1.6 users.

Do you have any thoughts on how to do that?
