There are two issues in ICC_Profile related to unnecessary data copying:
1. ICC_Profile.getInstance(byte[] data) method copies the profile header for validation. This copy appears redundant since the original data array is used later(added by the https://bugs.openjdk.org/browse/JDK-8347377).
2. Some code use getData(icSigHead) to get the header. This method always creates a new array. it is preferable to use getData(cmmProfile(), icSigHead), to avoid the extra copy.
