dev.functional suite on jdk8/mac/x64 is hitting 25 hour timeout

[sxa]

This job seems to hit the limit consistently: https://ci.adoptium.net/job/Test_openjdk8_hs_dev.functional_x86-64_mac/

In the code below the 02:37 and 03:31 times are from a 25 hour gap, not a one-hour gap:

02:37:44  + [[ jdk == \j\d\k ]]
02:37:44  + [[ incompatiblefalse == \c\o\m\p\a\t\i\b\l\e\t\r\u\e ]]
02:37:44  + [[ incompatiblefalse == \i\n\c\o\m\p\a\t\i\b\l\e\f\a\l\s\e ]]
02:37:44  + run_swing_component_test_unset incompatible false
03:31:36  Cancelling nested steps due to timeout
03:31:36  Sending interrupt signal to process
