Description
JDK uses LCMS as a default colour management module. So the test ColConvTest.java expects that every profile is generated by LCMS. That does not look correct. 
For example if some other profile (not generated by LCMS is used) the following tests will be failed even if LCMS library still used for colour conversion:

sun/java2d/cmm/ColorConvertOp/ColConvCCMTest.java 
sun/java2d/cmm/ColorConvertOp/MTColConvTest.java

JDK uses LCMS as a default colour management module but the test sun/java2d/cmm/ColorConvertOp/ColConvTest.java has some redundant LCMS check. In particular the method isOpenProfile() retrieves profile header and expects to see ‘lcms’ ID there. It used to be OK until recent LCMS update where the CMM started to keep original profile ID instead of writing ‘lcms’ to returned header. In other words starting from LCMS 2.16 if NOT LCMS-generated profile is used the test ColConvTest and related tests likely will fail.
