RFR: 8286398: Address possibly lossy conversions in jdk.internal.le

[Adam Sotona]

This patch is a part of general effort to address possibly lossy conversions in JDK before the relevant javac lint warning is enabled.
Addition of explicit casts from ints to shorts is proposed here, with respect to the original library code.
Please review.

Thank you,
Adam
