compile infinispan with 1.5 and run it with 1.6?

[amalrajvinoth]

Hi All,

is it possible compile infinispan src with jdk 1.5 and use jdk 1.6 at runtime?

if so what is the change required in pom.xml for mvn build?

thanks in advance.

Hi Amal,

sorry that's not possible. Why would you do that anyway?

Hi sanne,

sorry that's not possible. Why would you do that anyway?

Yes. it is not possible, but  by doing cross compilation with jdk6 using -target="1.5", so the classes will be compatible

for compilation with jdk1.5. but runtime should be jdk1.6.

thanks, Amal raj.

I haven't tried this.  Give it a go, your mileage may vary, let us know how it works for you.  :-)

Hi Manik,

After successful cross compilation, It is giving problem at run time when a new node joins

Hi, I'm quite confused on what you're doing with cross-compilation. You're running it on Java6 right? Then why do you need to recompile at all?

[amalrajvinoth]

Hi Sanne,

I've a situation where compilation should be dobe by jdk5 and runtime jdk6.

So by doing cross compilation, i made infinispan jars compatible for jdk5.

But runtime i'm getting the above error.

thanks, amal raj.
