Affects: 6.0.x, 6.1.x

From 5.3.x to 6.0.x, the implementation of filesystem-searching in PathMatchingResourcePatternResolver was changed from a recursive call to java.io.File.listFiles() to a single call to java.nio.file.Files.walk(rootPath). This changed the default behavior so that PathMatchingResourcePatternResolver.getResources("file:./thisisasymlink/*.txt") no longer works.

The java.nio.file.Files.walk method can follow symlinks, but that behavior must be requested by supplying the FileVisitOption.FOLLOW_LINKS option like this: Files.walk(rootPath, FOLLOW_LINKS)
