------------------------------------

Summary: No longer java 1.7 compatible
Key: MAHOUT-1966
URL: https://issues.apache.org/jira/browse/MAHOUT-1966
Project: Mahout
Issue Type: Bug
Reporter: Trevor Grant


When building ViennaCL or OMP modules with oracle java 7 we get the following errors:
```
[ERROR] /home/travis/build/rawkintrevo/mahout/viennacl/src/main/scala/org/apache/mahout/viennacl/opencl/javacpp/CompressedMatrix.scala:33: error: in class CompressedMatrix, multiple overloaded alternatives of constructor CompressedMatrix define default arguments.
[ERROR] final class CompressedMatrix(defaultCtr: Boolean = true) extends Pointer {
[ERROR] ^
[ERROR] /home/travis/build/rawkintrevo/mahout/viennacl/src/main/scala/org/apache/mahout/viennacl/opencl/javacpp/DenseColumnMatrix.scala:37: error: in class DenseColumnMatrix, multiple overloaded alternatives of constructor DenseColumnMatrix define default arguments.
[ERROR] final class DenseColumnMatrix(initDefault:Boolean = true) extends MatrixBase {
[ERROR] ^
[ERROR] /home/travis/build/rawkintrevo/mahout/viennacl/src/main/scala/org/apache/mahout/viennacl/opencl/javacpp/DenseRowMatrix.scala:32: error: in class DenseRowMatrix, multiple overloaded alternatives of constructor DenseRowMatrix define default arguments.
[ERROR] class DenseRowMatrix(initDefault: Boolean = true) extends MatrixBase {

[ERROR] /home/travis/build/rawkintrevo/mahout/viennacl/src/main/scala/org/apache/mahout/viennacl/opencl/javacpp/VCLVector.scala:30: error: in class VCLVector, multiple overloaded alternatives of constructor VCLVector define default arguments.
[ERROR] final class VCLVector(defaultCtr: Boolean = true) extends VectorBase {
[ERROR] ^
```

This is alleviated by moving to openjdk8

Trevor Grant commented on MAHOUT-1966:
--------------------------------------

Upon digging into this further- I think it may be more scala related than java... putting issue on hold- I think java7 may continue to suffice.
