Prior to this commit, combining the "/*" and "/x/y" path patterns would result in a `StringIndexOutOfBoundsException`. This commit fixes this problem and revisits the implementation for better consistency: * "/*" + "/x/y" is now "/x/y" * "/x/*.html" + "/y/file.*" is now rejected because they don't share the same prefix. This change also adds the relevant Javadoc to the `PathPattern#combine` method. Fixes gh-34986
