Bugzilla Bug 196080

I tried to build ant-core-1.7.0 with ecj today. Gentoo uses a "custom"
build.xml that uses source=1.2 as parameter for ant. Ecj rejects this source
level with the message:

build-core:
Compiling 50 source files to
/var/tmp/portage/dev-java/ant-core-1.7.0/work/apache-ant-1.7.0/build/classes
source level should be comprised in between '1.3' and '1.6' (or '5', '5.0',
..., '7' or '7.0'): 1.2

It would be good to use source=1.3 in this case.

Reproducible: Always

Steps to Reproduce:

I thought the ant-core ebuild built it always with javac?

Using gcj to build ant-core it's build with ecj first.

I'm seeing the same issue.

At the end of the build, the following is emitted:

!!! When you file a bug report, please include the following information:
GENTOO_VM=gcj-jdk-4.3  CLASSPATH="."
JAVA_HOME="/usr/lib/gcj-4.3.0_alpha20070921"
JAVACFLAGS="-source 1.4 -target 1.4" COMPILER=""
and of course, the output of emerge --info

The interesting part is the JAVACFLAGS="source 1.4 -target 1.4"

Looking at the eclasses, I'm thinking that java-pkg_get-source and
java-pkg_get-target are being set to 1.4.  I did not see where javac.source and
javac.target properties are being rewritten in the build.xml.

I tried overriding JAVA_PKG_WANT_SOURCE.  The original error didn't change (but
the JAVACFLAGS did reflect the new value).

Some relevant lines from
/var/tmp/portage/dev-java/ant-core-1.7.0/work/apache-ant-1.7.0/build.xml:

Patches build.xml to use 1.3, not 1.2

Ebuild using ecj.patch

The patch I just uploaded modifies the relevant lines in build.xml that cause
ecj to fail.

Or you add 'java-ant_bsfix_one build.xml' at the end of src_unpack().
But please fix this annoying problem, thanks! :)

Adding 

sed -i 's#1\.2#1.3#' build.xml

to the end of src_unpack also solves this.
Why is this being built with such an old bytecode version in the first place?

That's the right way :) Fixed in CVS in ant-core-1.7.1-r1, thanks!
