Java Unlimited Strength Policy is no longer a thing

[marschall]

Java Unlimited Strength Policy is no longer a thing and enabled by default. See

• JDK-8170157 Enable unlimited cryptographic policy by default in Oracle JDK builds
• Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files Download

  The unlimited policy files are required only for JDK 8, 7, and 6 updates earlier than 8u161, 7u171, and 6u181. On those versions and later, the stronger cryptographic algorithms are available by default.

The current versions of JDK 8, 7, and 6 are 8u302, 7u312, and 6u119. It was always enabled on JDK 11 and 17.
