Re: [Help-glpk] [Fwd: Jdk Version required for glpk-4.49]

Note that if you require to run this on an earlier version of the JVM
you can recompile it with javac using the
 -source 1.4 (or whatever version you want) option. 

see https://blogs.oracle.com/darcy/entry/bootclasspath_older_source

for full details.
