NoSuchMethodError: java.nio.ByteBuffer.position(I)Ljava/nio/ByteBuffer about osm-garmin

[Wouter1]

There appears to be a number of version conflicts in the pom.

1. xerces 4.11 conflicts with geotools that uses some sublibrary of xerces 2.4.0 internally
2. jdom b9 can't beused because geotools uses jdom 1.0
3. junit 4.11 can't be used because some genius at xpp3 hard included junit 4.7 in their distro...
   But after replacing all these libraries with older libraries, the junit test fial
   . 5 errors 22 warnings, errors like

java.lang.NoClassDefFoundError: Could not initialize class uk.me.parabola.mkgmap.build.LocatorConfig

java.lang.UnsupportedOperationException: setXIncludeAware is not supported on this JAXP implementation or earlier: class org.apache.xerces.jaxp.SAXParserFactoryImpl

Fixed the dependency conflicts by ecluding xerces from geotools and including a different working version

[Wouter1]

But that did not resolve the NoSuchMethodError

[Wouter1]

Checking the code. In line 147 there is this

	header.position(OFF_SIGNATURE);

where OFF_SIGNATURE = 16

The error is weird, java does have a position(int) function built in? And there is nothing overriding java.nio (checked the jar).

Maybe this netty/netty#9880 or https://stackoverflow.com/questions/48693695/java-nio-buffer-not-loading-clear-method-on-runtime
Is this a bug in the Eclipse built-in compiler?

Yes, it is a bug in the Eclipse compiler!

If I compile just with maven on java8 from commandline, the tool just works fine.
