Bug 571024 - [performance] Avoid replaceAll(regExp,)

Avoiding regular expressions for simple character replacements.
String.replaceAll() is twice as slow as String.replace()
and uses far more ephemeral memory allocation
which result in GC pause times for big projects.
This occurance was not a particular hot spot 
but was identified during mass-change.

JDT Core

This is the core part of Eclipse's Java development tools. It contains the non-UI support for compiling and working with Java code, including the following:

  • an incremental or batch Java compiler that can run standalone or as part of the Eclipse IDE
  • Java source and class file indexer and search infrastructure
  • a Java source code formatter
  • APIs for code assist, access to the AST and structured manipulation of Java source.

For more information and important links, refer to the [JDT wiki page] 1 or the [JDT project overview page] 2.
