Subject RE: Tests fail to compile on JDK 1.4?
Date Tue, 02 Jun 2009 06:49:24 GMT
Hi Shai,


it is set to 1.4. The problem, during compilation, the class library
(rt.jar) of the installed JDK contains new methods from 1.5, so even when
you set the compiler level to 1.4, it still checks all methods/classes
against the current rt.jar.

We had some discussions about it, the easiest is, to set the bootclasspath
in the <javac/> task to an older rt.jar during compilation. Because this
needs updates for e.g. Hudson (rt.jar missing) we said, that the one, who
releases the final version should simply check this before on the
compilation computer in the release process.

My fault. I didn't notice Class.getSimpleName() exists since Java 1.5.
I wonder if it's possible to set the compiler level to 1.4 in the build.xml.
This is needed for core, but for contrib it should be 1.5. I'll check if
that's possible and post a patch if it is.

Yes I'm seeing this too.  I thought I had fixed it, with LUCENE-1655,
but somehow I didn't...

I'll fix.
