Interesting... I'm thinking that to get our code base to work with Java 11, we'll need to scan our code for all uses of ByteBuffer, and if any of those uses calls the 7 changed methods, we'll need to fix those; is that your take?
I did scan our code, and found some uses of ByteBuffer, but haven't yet explored further to see if we use these methods... -Marshall On 11/7/2018 9:06 AM, Richard Eckart de Castilho wrote: > I'm trying to test the RC. > > The UIMAv3 core builds nicely under Java 11. > I can also use it as a dependency for uimaFIT v3.0.0-SNAPSHOT and build under > Java 8. > However, when I try to build DKPro Core v2 against UIMAv3.0.1 and uimaFIT > 3.0.0-SNAPSHOT, I get > problems such as this: > > [ERROR] > test4Preinitialized(de.tudarmstadt.ukp.dkpro.core.io.bincas.BinaryCasWriterReaderTest) > Time elapsed: 0.177 s <<< ERROR! > java.lang.NoSuchMethodError: > java.nio.ByteBuffer.position(I)Ljava/nio/ByteBuffer; > at > de.tudarmstadt.ukp.dkpro.core.io.bincas.BinaryCasWriterReaderTest.read(BinaryCasWriterReaderTest.java:527) > at > de.tudarmstadt.ukp.dkpro.core.io.bincas.BinaryCasWriterReaderTest.test4Preinitialized(BinaryCasWriterReaderTest.java:150) > > It seems these are caused by the addition of new methods in JDK9.
