When the JDK is installed in a directory whose name ends with an exclamation mark ('!'), BreakIterator.getSentenceInstance crashes with an InternalError.

To reproduce, use this test code:
-----
import java.text.BreakIterator;
import java.util.Locale;

public class BreakIteratorTest {

    public static void main(String[] args) {
        BreakIterator.getSentenceInstance(Locale.ENGLISH);
    }

}
-----

And run it like this (please note the '!' in the JDK path):
$ /tmp/jdk\!/jdk1.7.0_25/bin/javac BreakIteratorTest.java
$ /tmp/jdk\!/jdk1.7.0_25/bin/java -classpath . BreakIteratorTest
Exception in thread "main" java.lang.InternalError: java.io.IOException: Stream closed
        at java.text.BreakIterator.createBreakInstance(BreakIterator.java:620)
        at java.text.BreakIterator.getBreakInstance(BreakIterator.java:565)
        at java.text.BreakIterator.getSentenceInstance(BreakIterator.java:546)
        at BreakIteratorTest.main(BreakIteratorTest.java:7)
