[SOLVED] Update Oracle JDK from 7u-51 to 7u-55 or to 8u5

tronayne · 04-17-2014, 01:38 PM

Oracle released updated Java packages 14 April: 7u-55 and 8u5 (I don't use OpenJava because it doesn't work right with applications I have, in particular, DSpace).

So, I'm wondering, is an update to 8u5 feasible and compatible with 7u55? Or wait a while before moving to Java 8 (I've just installed 7u55, no runs, drips or errors)?

Anybody with any experience?

Hello,

The JDK 8 is backward compatible with JDK 7. However, it would be better to read this page first.

If you want to install the JDK 8 with the slackbuild from SlackBuilds.org, you will have to update the variable VERSION (from 7u51 to 8u5) and change the line :

Code:

DVER=1.7.0_$(printf $VERSION | cut -du -f2)

to

Code:

DVER=1.8.0_05

Ah, looks some time with the development box; thanks for that link (I'm getting old, blinder than a bat and I didn't see it anywhere).

Well, I use the Slackbuild from the extra/java directory and automagically does the version, but good to know!

Thanks for the input.
