byte[] support in JPA entities

[Khare, Aparna]

Dear Colleagues,

   We have a use case where we would deploy our content in SAP Hana Cloud 
Platform (HCP).

We have a JPA entity which takes byte[] array. The olingo takes in dependency 
for commons-codec-1.6.jar. Whereas the HCP platform requires a dependency to  
commons-codec-1.4.jar .
Because of which we are encountering the below error



java.lang.NoSuchMethodError: 
org.apache.commons.codec.binary.Base64.isBase64(Ljava/lang/String;)Z

               
org.apache.olingo.odata2.core.edm.EdmBinary.validateLiteral(EdmBinary.java:59)

               
org.apache.olingo.odata2.core.edm.EdmBinary.internalValueOfString(EdmBinary.java:91)



I understand this is not a bug with olingo but we would request incase you can  
please change the code

instead of using isBase64(string) method which is not available in 
commons-codec 1.4, if you can switch to isArrayByteBase64(byte[]) which is 
present.

This way hopefully we would be able to resolve the issue.




Thanks,

Aparna
