icedtea-web: thread 'main' panicked at 'Error spawning JVM process'

Start by inspecting the icedtea-web package and reproducing the javaws.exe invocation on Windows. Compare the expected javaw.exe entry point with the installed javaws.exe and the reported JVM path. Done means identifying the package or executable-resolution change needed for JOSM to launch, then verifying it with the reported setup.

Bug Report

My apologies if this issue is a result of me not knowing what I'm doing.

My goal is running JOSM (installed from the extras bucket). Running that after installation returns the error message:

Windows cannot find 'javaw.exe'. Make sure you've typed the name correctly, then try again.

JOSM is a JNLP application which required Java Web Start. Searching around, I found this should be provided by the icedtea-web package from the java bucket. However, installing that package doesn't do anything to the error JOSM returns.

Checking the IcedTea-web package, I do not find javaw.exe but I do find javaws.exe. However, running that returns this error:
