supported requirements are for example:

- 1.6* requires Java 6 (any update) [1.6, 1.6.0_45, 1.6.0_88]

- 1.6 requires Java 6 or higher [1.6, 1.6.0_45, 1.8, 9, etc.]

- 1.6.0 requires Java 6 (any update) [1.6, 1.6.0_45, 1.6.0_88]

- 1.6.0_45 requires Java 6u45 [1.6.0_45]

- 1.6.0_45 requires Java 6u45 or higher [1.6.0_45, 1.6.0_88, 1.8, etc.]

- 9 requires Java 9 (any update) [9.0.*, 9.1, 9.3, etc.]

- 9* requires Java 9 (any update) [9.0.*, 9.1, 9.3, etc.]

- 9 requires Java 9 or higher [9.0, 9.1, 10, etc.]

- 9.1 requires Java 9.1 (any update) [9.1.*, 9.1.2, 9.1.13, etc.]

- 9.1* requires Java 9.1 (any update) [9.1.*, 9.1.2, 9.1.13, etc.]

- 9.1 requires Java 9.1 or higher [9.1, 9.2, 10, etc.]

- 9.1.3 requires Java 9.1.3 [9.1.3]

- 9.1.3* requires Java 9.1.3 (any update) [9.1.3]

- 9.1.3 requires Java 9.1.3 or higher [9.1.3, 9.1.4, 9.2.*, 10, etc.]

- 10-ea requires Java 10 (early access release)

#

unsupported requirement patterns are for example:

- 1.2, 1.3, 1.9 Java 2, 3 are not supported

- 1.9 Java 9 introduced a new versioning scheme

- 6u45 known versioning syntax, but unsupported

- 9-ea*, 9-ea early access releases paired with */

- 9., 9.*, 9. version ending with a .

- 9.1., 9.1.*, 9.1. version ending with a .

- 9.3.5.6 4 part version number is unsupported
