GNU Classpath 1.0 will be fully compatible with the 1.1 and 1.2 API
specifications, in addition to having significant (>95%) compatability
with the 1.3, 1.4, 1.5 and 1.6 APIs. Our target for this release will
be to be fully API compatabile with the core of 1.5 (i.e. java.*, not
javax.*) and to have a number of significant applications (to be
determined by user input) running well. The vast majority of the 1.4
and 1.5 APIs will be available, along with a stable API for
interacting with virtual machines. The latter is likely to involve
some interaction with the
OpenJDK challenge for a
new virtual machine interface
.
Current snapshot releases have implementations for most Java packages. The
live JAPI results above give further details on this. Major missing packages
with respect to 1.6 are in the javax.* namespace, including the web services
APIs (JAXWS). There is no current plan to implement these, given their
existing presence as a distinct element in
OpenJDK
. Thus, our preference
is to get this working with GNU Classpath rather than implement the entire API
from scratch.
What we implement is largely based on user feedback. If there is a particular
API that is critical to your use of GNU Classpath, then please let us know. We
can then adjust our priorities accordingly.
