thanks

i want client jars work (compile/run) in java 6 way can achieve this?

if have source code, can try compiling code on java 6 build platform. however, there no guarantees compile , run as-is:

• the code may use java 7 language constructs.

• the code may use java 7 specific classes or methods.

the bad news there no magic way deal compilation errors arising above. need hand translate java 7-isms java 6 compatible source code.

but news if code does compile on java 6 jdk, there pretty chance run on java 6 jre.

if don't have access source code, problem much, harder

it theoretically possible translate bytecode earlier version, tools doing tend have significant limitations. here possible leads:

• retrotranslator translates java 1.5 bytecodes (some) older platforms.
• retroweaver same thing.

note i've not managed find "retro" tool translates java 7 java 6. (either nobody has done work, or there java 7 makes problem intractable.)
