roundtrip java whole package : wrongly detected syntax error

[tibolpol]

EDIT duplicate of #123

21Mo project written with bouml 4.22.2 and stored with iso8859-1,
trying to roundtrip a whole package with current DoUML version

[...] Nomenclature.java line 291 { is missing
Rountrip aborted!

• roundtrip the same Nomenclature.java alone is OK
• roundtrip other packages give same syntax error, whatever the source

  NObject.java line 1149 { is missing
  Rountrip aborted!

Same error after conversion of the storage from iso8859-1 into utf-8
