Bugzilla Bug 23874

2 Problems:
a) 'emerge ant' prints errors in the compile stage, but happily continues 
    and merges the broken ant to the live filesystem

b) The ant sources up to and including 1.5.3 cannot be compiled with the 
   new sun-jdk-1.4.2, as there have been incompatible changes in at least 
   one internal class.

Ant's build.sh causes a) by exiting with status 0 in spite of errors.
The ebuild calls "build.sh || die", so emerge goes on installing.

Problem b) is solved in the ant sources from CVS.

I will add patches solving both issues for ant-1.5.3 soon.

Reproducible: Always
Steps to Reproduce:
1. get the ebuild and related files from PR 23701
2. emerge sun-jdk-1.4.2 ant set it as system-vm
3. emerge ant

Actual Results:  
The ant build-script complains about 2 errors and finally says 
| ... Failed Building Ant Distribution !
| Bootstrap FAILED

emerge goes on:
| >>> dev-java/ant-1.5.3-r4 merged.

The installed ant ist totally broken:
$ ant
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/tools/ant/Main



Expected Results:  
The emerge should not continue with install/qmerge but fail.

Backport from ant CVS sources. 
Patched ant-1.5.3 sources will compile with all JDKs including sun-jdk-1.4.2.

i will check these patches and if they work ok. 
then i can movo to testing sun-jdk-1.4.2 and ant 1.5.3 with the patches. 

Checked those files, and worked like a charm. 
I tested the most important features of ant, build it with any jdk, and it 
worked very well. So putting it on testing.
