Erst seit kurzem steht der neueste Build für Java 7 Meilenstein 5 zur Verfügung und schon rumort es in der Community. Scharfe Kritik übt unter anderem Mark Wielaard, der unter anderem in den Projekten GNU Classpath und GNU Compiler for Java arbeitet. Grund für den Unmut ist das Fehlen einer Open-Source-Lizenz bei den Binary-Downloads des Builds.
I wanted to research this JDK7 M5 and compare it to the work we did on OpenJDK and IcedTea, but apparently I am not allowed to… There is no reason for Sun to act in this anti-social way. There are free replacements for the previously encumbered binary blobs (thanks IcedTea!). So anybody that wants to can distribute a completely free version. And redistributing other peoples contributions under such draconian one-sided terms is totally unnecessary (and rude!). (Mark Wielaard)
Wielaard weiß zwar, dass Sun diese Software-Politik wegen des Sun Contributor Agreements (SCA) fahren darf, findet sie aber unfair. Derweil erklärt Dalibor Topic, Java F/OSS Ambassador bei Sun in seinem Blog, warum die Binary-Downloads nicht Open Source zur Verfügung stehen:
The logic behind it is rather simple: In order to give anyone interested an option to contribute feedback, bug reports, testing, etc. to OpenJDK in general and JDK 7 development in particular regardless of their preference for or aversion to open source, Sun Microsystems offers its own builds of JDK 7 under a non-open-source license, while at the same time offering the OpenJDK source code used to create those builds under an open source license to enable users with a preference for open source builds to make their own. (Dalibor Topic)
