Description
String performance improvements would be good for pack200, since this will speed up build process
for internal products such as JDK, JavaFX, NetBeans, as well as other external and user products builds.

Comments
The vast majority of time we do spend in one method - String[] ConstantPool.structureSignature(String) Just by optimizing this method we might gain a noticeable performance improvement.
