Cannot run stream2es with java 1.6 anymore on mac

[brwe]

When running stream2es with java version "1.6.0_51" on mac (OS X 10.8.4), I get the call stack below. Works fine with 1.7 for me.

To reproduce, run

  export JAVA_HOME=$(/usr/libexec/java_home -v 1.6)

,to set the java version to 6 (mine says: java version "1.6.0_51" afterwards) an then

  echo '{"foo":1}' | stream2es

Message is:

While building a 1.6 version I realized I started using a class from java.nio.* that isn't compatible. Perhaps we simple need to document that we support 1.7+? I can't think of a reason anyone would be stuck with 1.6 for this application.

[timhaines]

I just tried downloading Java 1.7 from java.com in order to run this, and the installation failed for me.

[brwe]

@drewr I think a note in the documentation would suffice.

@timhaines what OS are you trying here? I mean google should take you far here, what's the error?

[timhaines]

@s1monw OSX Mountain Lion. Just got it resolved. For some reason I was missing a /Library/PreferencePanes folder, so the Java installer was dying because of that. After I created that folder, the installer worked. Then I had to manually update ~/.bash_login to change JAVA_HOME from the 1.6 location to 1.7. Ugh. I'm excited to get back into hammertime now it's resolved.

@drewr I mean this is just because you use the FilePermissions that are new in Java 7 can't we use File.setReadable(boolean, boolean) etc. if those classes are not available ie. detecte / fallback to java 6 and do best effort?

@timhaines cool stuff 👍
