Hello classpath developers,
I'm the maintainer of an ONC/RPC package for Java, which is available
under the LGPL (acplt.org/ks/remotetea.html). Within the jrpcgen
protocol compiler, which is part of this ONC/RPC package, I would like
to use the implementation of SHA-1 just to create serialization UIDs for
the classes generated by the protocol compiler.
The classpath package provides an implementation of SHA-1 in
gnu.java.security.provider.SHA. For the purposes of the jrpcgen protocol
compiler I would like to use the SHA class, with special adaption to the
protocol compiler, that is, I want to remove general parts that are not
necessary in this particular situation. The changed implementation would
then be moved to a different package (of course).
The SHA implementation in classpart is provided under the GPL. However,
my package is distributed under the terms of the LGPL. I'm not sure
whether the additional clause
As a special exception, if you link this library
with other files to produce an executable, this
library does not by itself cause the resulting
executable to be covered by the GNU General Public
License
mentioned in the SHA.java source file would allow me to distribute a
modified version together with the LGPL'd ONC/RPC package without
running into legal (and social) problems (especially regarding jar files
containing the class code).
Is it possible to get permission from the classpath developers to
distribute a modified SHA.java, probably under the LGPL?
Thank you very much,
Harald
