I guess this is needed here, in addition to

openapi-generator/modules/openapi-generator/src/main/java/org/openapitools/codegen/languages/AbstractJavaCodegen.java

Line 615 in 1280221

if (isReservedWord(name) || name.matches("^\\d.*")) {

if the name is all uppercase and thus matches this early return:

openapi-generator/modules/openapi-generator/src/main/java/org/openapitools/codegen/languages/AbstractJavaCodegen.java

Lines 594 to 596 in 1280221

if (name.matches("^[A-Z0-9_]*$")) {
return name;
}

name = "_" + name;
}

// if it's all uppper case, do nothing
if (name.matches("^[A-Z0-9_]*$")) {
return name;
