Building Redline Smalltalk on Fedora 15 fails as follows:

  [INFO] Compilation failure

  /home/penberg/redline-smalltalk/src/main/java/st/redline/SourceFileFinder.java:[11,20] generics are not supported in -source 1.3
  (use -source 5 or higher to enable generics)
	private static List<String> sourceFilePaths;

  /home/penberg/redline-smalltalk/src/main/java/st/redline/SourceFileFinder.java:[39,29] for-each loops are not supported in -source 1.3
  (use -source 5 or higher to enable for-each loops)
		for (String sourceFilePath : sourceFilePaths())

To fix the issue, update POM to use Java 1.5 for compilation.
