Method Detail

smartPathSplit

public static String[] smartPathSplit(String pathStr)

Split a path on File.pathSeparator (':' on Linux, ';' on Windows), but also allow for the use of URLs with protocol specifiers, e.g. "http://domain/jar1.jar:http://domain/jar2.jar". This is really not even handled by the JRE, in all likelihood, but it's better to be robust.

getRtJarPath

public static String getRtJarPath()

Get the path of rt.jar

logJavaInfo

public static void logJavaInfo(LogNode log)

Log the Java version and the JRE paths that were found.

isJREJar

public static boolean isJREJar(String filePath,
                               LogNode log)

Determine whether a given jarfile is in a JRE system directory (jre, jre/lib, jre/lib/ext, etc.).

isJar

public static boolean isJar(String path)

Returns true if the path ends with a jarfile extension, ignoring case.

leafName

public static String leafName(String path)

Returns the leafname of a path.
