Java Apache Commons WordUtils.wrap() throws SecurityException during runtime

Question

Allright so after implementing the org.apache.commons.lang3.text.WordUtils class I was hoping to be able to use the WordUtils.wrap(String str, int width) function. But I reached a speed bump.

I was able to compile this program (which I should mention is an applet) without a single problem. I just had to set a CLASSPATH environment variable to reference the apache jar file, and then through appletviewer get the program to run. However when I reach the part of the code that uses the WordUtils.wrap() function everything turns sour and I get about 20 lines of runtime-errors on the command prompt.

Errors:

Here is the line of code that causes all this trouble:

String strWrap = WordUtils.wrap("A really really really really really long sentence.", 50);

What's happening here?

Answer 1

How about passing the line separator as an argument to bypass the SystemUtils access:

String strWrap = WordUtils.wrap("A really really really really really long sentence.", 50, "\n", false);

Answer 2

Your code uses WordUtils which calls SystemUtils in order to find the line separator used by your system:

newLineStr = SystemUtils.LINE_SEPARATOR;

SystemUtils is trying to read system properties that an applet is probably not allowed to read, due to the security restrictions in a browser.

The documentation for SystemUtils says:

If a system property cannot be read due to security restrictions, the corresponding field in this class will be set to null and a message will be written to System.err
