java.text.MessageFormat.applyPattern(String newPattern) does not throw any
exceptions for illegal patterns.
Javadoc says:

 * If a pattern is used, then unquoted braces in the pattern, if any, must match:
 * that is, "ab {0} de" and "ab '}' de" are ok, but "ab {0'}' de" and "ab } de" are
 * not.

Here is the test demonstrating the bug:

-----------------Test.java------------------------
import java.text.*;

public class Test {
    public static void main (String args[]){
        MessageFormat mf = new MessageFormat("initial pattern");
        String illegalPattern = "ab { '}' de";
        mf.applyPattern(illegalPattern);
        System.out.println("illegal pattern: \"" + illegalPattern + "\"");
        System.out.println("toPattern returns: \"" + mf.toPattern() + "\"");
    }
}
---------Output from the test---------------------
illegal pattern: "ab { '}' de"
toPattern returns: "ab "
