Unable to execute command with execution bit set

Hello all.

I'd like to setup an Alpine based JAVA 1.5 docker image (base on alpine from docker hub) for my apps execution/development environment, but the installer fail to run due to some checking (df command returns nothing). Then I try to extract the image from the .bin file and add execution permission to the extracted image, and it gave me something like ELF... not found. I've double check for the architecture according to my downloaded version of JRE installer to make sure they're the same.

I'm wonder how peoples install JRE 7/8 to alpine? why not 5? and the most important, what can I do beside giving it up?

Thanks in advance.
