Thanks Anestis for your analysis and detailed feedback.
@J. Aravind: I hope this is helpful. You should be able to reproduce the
problem with a recent version of Java. Generally speaking you want to
make sure that your package is compatible with reasonably recent
versions of Java. FWIW here are the versions of Java installed on the
Bioconductor build machines:

Hello,
On line 1289 of melting.R you call the keyset() method of opts_melt (which is a
HashMap).
This method in Java until 11, return a private AbstractSet (KeySet).
On line 1290 of melting.R you call iterator() method of the KeySet object you
got on the previous line.
Problem is that this KeySet is private and this call through reflexion isn’t
valid, hence the exception.
They changed this in java 11 where the returned AbstractSet is public.
So solution is either use java >11
or change your code in melting.R to not call the iterator() method of keyset
(which is a private AbstractSet).

Subject: [Bioc-devel] Issue with a package dependent on rJava
Dear Bioconductor Developers,
My package `rmelting` is failing to build on release (3.15) and devel (3.16)
versions for the following systems.
Bioconductor 3.15
- palomino3 (Windows Server 2022 Datacenter / x64)
Bioconductor 3.15
- palomino4 (Windows Server 2022 Datacenter / x64)
- lconway (macOS 12.5.1 Monterey / x86_64)
The error message is as follows.
```
* creating vignettes ... ERROR
--- re-building 'Tutorial.Rmd' using rmarkdown_notangle
.
.
.
.
.
Quitting from lines 195-197 (Tutorial.Rmd)
Error: processing vignette 'Tutorial.Rmd' failed with diagnostics:
java.lang.IllegalAccessException: class RJavaTools cannot access a member of class
java.util.HashMap$KeySet (in module java.base) with modifiers "public final"
--- failed re-building 'Tutorial.Rmd'
SUMMARY: processing the following file failed:
'Tutorial.Rmd'
```
I am unable to replicate the same on my end.
It seems to be an issue with java. The package is a low level interface to a
software written in Java 1.5 using `rJava`. I have tried with different java
versions upto 1.8.
Any pointers or suggestions to fix the same will be appreciated.
