We are proud to announce the release of IcedTea6 1.5.

The IcedTea6 project provides a harness to build the source code from 
OpenJDK6 ( using Free Software build tools.

What's New?
- Static trace support through systemtap.
  When given the configure option --enable-systemtap IcedTea will build
  hotspot with the dtrace static markers enabled and install an hotspot
  tapset that can be used to dynamically trace execution of java
  applications at runtime. See the tapset/hotspot.stp file for
  documentation of the various trace points and arguments available.
- Allow building of other virtual machines besides the default VM. 
  virtual machines on architectures where hotspot is available are cacao
  and zero (or shark), and cacao, where zero (or shark) is available. It's
  not possible to build cacao as the default VM, and zero as additional VM.
- Update to latest HotSpot minor build (hs14b10-->hs14b15) from the new
  HotSpot Express repository.
- Updated to OpenJDK b16 build.
- VisualVM updated to 1.1.1.
