NoSuchMethodError when run on Java 6 #28

Closed amjjd closed 10 years ago

amjjd commented 11 years ago

Scanner throws this when run on JDK6:

Exception in thread "main" java.lang.NoSuchMethodError: java.nio.CharBuffer.subSequence(II)Ljava/nio/CharBuffer;
    at org.freecompany.redline.payload.CpioHeader.readChars(CpioHeader.java:158)
    at org.freecompany.redline.payload.CpioHeader.readSix(CpioHeader.java:148)
    at org.freecompany.redline.payload.CpioHeader.read(CpioHeader.java:188)
    at org.freecompany.redline.Scanner.main(Scanner.java:59)

This is caused by this addition in JDK7: http://bugs.sun.com/view_bug.do?bug_id=6733145

Building with JDK6 or JDK5 fixes it, but I have to verify that a version built using JDK6 will work when run using Java 7 - on a Snow Leopard Mac at the moment so I can't check.

Thanks, will look into this.

The upcoming release will be built with Java 6 to correct this.

I am under the impression that version 1.1.14 was still built using JDK7 as this bug is still occurring:

java.lang.NoSuchMethodError: java.nio.CharBuffer.subSequence(II)Ljava/nio/CharBuffer;
        at org.freecompany.redline.payload.CpioHeader.readChars(CpioHeader.java:162)
        at org.freecompany.redline.payload.CpioHeader.readSix(CpioHeader.java:152)
        at org.freecompany.redline.payload.CpioHeader.read(CpioHeader.java:192)
        at org.freecompany.redline.payload.CpioHeader$read.call(Unknown Source)

Edit: When I do a file command on each class file in the jar I recieve the output: 

<ClassName>.class: compiled Java class data, version 49.0 (Java 1.5)

This leads me to believe that the class files may have been generated for a Java5 bytecode format, however using Java7 libraries.

When is the expected release of 1.1.15?

If it is not imminent, would it also be possible to re-release the older versions, at least 1.1.14 (and ideally back to 1.1.12) as redline-1.1.14-java6.jar as built by a Java 6 JDK?

Fortunately, everything seems to work fine under Java 7 when compiled with a Java 6 JDK.

It's easy to build with java 6, but it's the publication to Maven Central that would need to be officially done.
