.nbbugzilla-components entries fixed in ef3f1d13dd48 Lahváči I wanted to CC you to help me with the issue... "error: type ServiceReference does not take parameters" is a nonsence, since OSGi4.3, the ServiceReference type takes parameters. Report a JDK bug or use some new JavaC. (In reply to comment #2) > Lahváči I wanted to CC you to help me with the issue... > > "error: type ServiceReference does not take parameters" is a nonsence, since > OSGi4.3, the ServiceReference type takes parameters. It is questionable whether the ServiceReference actually take type parameters (from the compiler point of view - whats written in the OSGi spec does not matter much). The problem is that the classfiles have version 48 (=1.4), and use the Signature attribute, which contains the type parameter information and was introduced in version 49 (=1.5). The javac ignores such attributes since 7 (and that has apparently been backported to OpenJDK 6): " [nb-javac] /media/src/space/src/nb/outgoing/nbbuild/build/public-package-jars/org-netbeans-libs-osgi.jar(org/osgi/framework/ServiceReference.class): warning: [classfile] Signature attribute introduced in version 49.0 class files is ignored in version 48.0 class files" To the best of my knowledge, this has been introduced intentionally: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6817950 Actually, the current warning has obviously been added ex post, see Jesse's: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6966357 which was duplicated to an enhancement that actually implemented the warning: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6999210 > > Report a JDK bug or use some new JavaC. Newer javac won't compile netbinox, while older will - as I noted above, it cannot be compiled using JDK7. I was not able to check with JDK8, but I still see the check in javac sources, so I am quite confident the behavior is still the same. (I see that there might be confusion due to fact that the OpenJDK 6 version was 1.6.0_22, while the closed one was 1.6.0_24 - I think that these version numbers are independent, and cannot be compared.)

I've simulated the failure with java version "1.7.0_147-icedtea" I am using raw types since: ergonomics#35e07169f6bc You should report to the OSGi consortium that compliant compilers will reject their attempt to sneak generic types into a -target 1.4 JAR. Integrated into 'main-golden', will be available in build *201203010400* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress) Changeset: http://hg.netbeans.org/main-golden/rev/35e07169f6bc User: Jaroslav Tulach <jtulach@netbeans.org> Log: #208666: Make sure netbinox compiles on 1.7.0_147-icedtea |
Created attachment 115963 [details] Failed build of netbinox. I cannot build netbinox module (sorry if this is not the correct category - there is no entry for netbinox in .nbbugzilla-components) using OpenJDK, or JDK1.7 - closed JDK 1.6 is OK.
