JDeveloper 11g ( Startup Mystery - JDK 1.6.0_24 Not Supported (1.6.0_35 Required)

New JDeveloper 11g ( on Windows fails to start with embarrassing error after fresh installation, this is known issue and Oracle is fixing it. Seems like Oracle engineers missed it and released JDeveloper 11g ( with wrong JDK. Once you install JDeveloper 11g ( and try to start it, JDK error is reported - Java version 1.6.0_24 not supported. The minimum version required is 1.6.0_35 and JDEV startup stops, basically unusable:

If you go and check installation contents for JDeveloper 11g (, you will see only JDK 1.6.0_24 packaged. This looks like a mistake to me:

Workaround (until Oracle will fix it in JDeveloper 11g ( is to install required JDK 1.6.0_35 manually by yourself and point it during JDEV startup:

With manually installed JDK 1.6.0_35 JDEV works:

Still this is quite funny - why JDK 1.6.0_24 would be included if JDEV requires JDK version 1.6.0_35.

Hi Andrejus

So you're aware Oracle released another build 6436.1 to address the supported JDK issue.
