experiment, targeting java 11 (don't merge) with 5.4

[zspitzer]

Lucee currently still supports java 8, let's try targeting java 11 and see how the build performs

first run only has whitespace changes second run targets and tests with 11

[zspitzer]

first run (targeting 1.8)

Total Execution time: (549 s) Test Execution time: (541 s)

(5.4 doesn't report rough memory stats like 6+ does)

[zspitzer]

Second run (with target java 11)

Total Execution time: (325 s) Test Execution time: (315 s)

[zspitzer]

I re-run the 1.8 tests, just as I was curious about the huge difference

Total Execution time: (485 s) first run was (549 ms) Test Execution time: (476 s) first run was (541 s)
