validateJavaHome returns better message

[Martin-Zeithaml]

For Java 17, the function java.validateJavaHome(); could return Java 17.0.0" 2024-01-0 (extra quote and incomplete date).

The original implementation was made for Java 8 with different output.

This fixes both cases:

• java version "1.8.0_321"
• java version "17.0.10" 2024-01-02

Tests:

java version "1.17.0" 2024-01-16 -> Java 17.0.10 2024-01-16 is supported.
java version "1.17.0"            -> Java 1.17.0 is supported.
java version "1.8.0_321"         -> ERROR: Java 1.8.0_321 is less than the minimum level required of Java 17.
