Knut Anders Hatlen updated DERBY-5840:
--------------------------------------
Attachment: derby-5840-03-aa-drda.diff
The network server is only supported on Java 5 and newer since 10.9. The
attached patch, derby-5840-03-aa-drda.diff, changes source and target level to
1.5 for all the code under java/drda (except the servlet) and adds type
arguments to declarations and constructor calls where it's required in order to
silence unchecked conversion warnings.
Some places the patch also removes casts that became unnecessary because of the
extra type information available to the compiler, but I didn't spend too much
time on tracking down code that could be simplified, as that didn't cause any
compiler warnings.
The code compiles with no warnings in my environment, and all the regression
tests passed.
