The ZipFileSystem initCEN method lacks two validation checks currently included in the corresponding ZipFile implementation:

That the END header's CEN length does not exceed the JDK array implementation limit. See JDK-8272746.

That the END header's total CEN entry count does not exceed the maximum number of CEN headers encodable within the CEN byte array. See JDK-8341625.

These checks should be added to ZipFileSystem such that the valodation logic is aligned across implementation.
