Description:
i have a simple sample of code:
{code:java}
String script = "import com.atlassian.jira.component.ComponentAccessor\n" +
"\n" +
"Set asdf1 = [\n" +
"\"abc\"\n" +
"] as Set\n" +
"\n" +
"Set asdf2 = [\n" +
"\"def\"\n" +
"] as Set\n" +
"\n" +
"Set asdf3 = [\n" +
"\"qwer\",\n" +
"\"wert\"\n" +
"] as Set\n" +
"\n" +
"Set asdf4 = [\n" +
"\"qwerty\"\n" +
"] as Set\n" +
"\n" +
"Set asdf5 = [\n" +
"\"asdvlkjn\",\n" +
"\"asdlvkasdlkvm\",\n" +

catch (Exception e) {

System.out.println(l1 - l);
}{code}
code parsing hangs for a long time.
but if i add ';' after every string like
{code:java}
] as Set{code}
so it will look like
{code:java}
] as Set;{code}
in groovy-script, it works fast.
the problem seems somewhere deep in ParserATNSimulator, its configurations or
predictive parsing at all (seems quite greedy) - randomly stopped debugger
shows that while it hangs:

i understand that the code of script could have errors (for example, import
could not be found or smthng else), but i think that the parser hanging is
quite abnormal
in pom tried both (separately ofc):
