JOSM crash on opening_times validator

[anonymous]

What steps will reproduce the problem?

1. JOSM seems to fail on opening times, so I narrowed it down to this one I'm trying to change
2. opening_hours=Apr-Oct Tu-Sa,SH Mo 10:00-16:00; Apr-Oct Su,PH 11:00-16:00
3. regular opening times, but also within the Apr-Oct period on Monday is School Holiday and any Public Holiday within that period

What is the expected result?

The validator may warn me on wrong syntax or accept it without crashing

What happens instead?

JOSM crash
