I think common-build.xml needs serious trimming.. I keep getting OutOfMemory even with 8GB RAM...I refactored common-build.xml to rid of serious baggage and now javac on src/java and src/test and junit seem to work flawlessly now
IVY calling a macro calling the actual taskdef with everything parameritised probably is the culprit..By replacing IVY macros with plain taskdefs I was able to run all 537 testcases with 4GB RAM

Migrated from [LUCENE-6162](https://issues.apache.org/jira/browse/LUCENE-6162) by Martin Gainty
Environment:
```
JDK 1.7.0_45
ANT 1.8.2
```

Start with common-build.xml and compare the Ivy macro/taskdef path with the reported javac and test targets. Run the src/java and src/test builds with the stated JDK and Ant versions, checking whether the FileNotFoundException or OutOfMemory condition is reproducible. Done means the build completes its 537 test cases without either failure.
