Describe the bug
During compilation, when generating code, the compiler fails with a stacktrace (repeated a couple of times). It's on a java-to-string-all-element call on the term Chars([TP]).

mb.stratego.common.StrategoExceptions$ExceptionalFail: Invoking Stratego strategy 'stratego2-strj-sep-comp' failed exceptionally

Project
This is when compiling a Stratego 2 project.

Versions
Spoofax 3 0.16.16

To Reproduce

strategies
  A :: TP
  A = topdown(try(B))

  // note how B is not marked TP. When B is marked TP this bug is worked around.
  B = id

Observed behaviour
The compiler gives no remark on inserted casts, warnings or errors but fails during compilation.

Expected behaviour
An error in A that it cannot prove TP for try(B).

Additional context
The stacktrace is probably not super useful since the problem occured earlier when the bad Java AST was built, but here it is:

Caused by: org.spoofax.interpreter.core.InterpreterErrorExit: Internal error: 'with' clause failed unexpectedly in 'java-to-string-all'
