[jboss-jira] [JBoss JIRA] (JASSIST-181) java.lang.RuntimeException: multiple descriptors? with javac 1.7
[
https://issues.jboss.org/browse/JASSIST-181?page=com.atlassian.jira.plugi...
]
Oleh Faizulin updated JASSIST-181:
----------------------------------
Workaround Description:
As workaround we have to change existing code @javassist.bytecode.Descriptor#toClassName
replace:
{noformat}
if (c == 'L') {
int i2 = descriptor.indexOf(';', i++);
name = descriptor.substring(i, i2).replace('/', '.');
i = i2;
}
{noformat}
with
{noformat}
if (c == 'L') {
if (descriptor.indexOf(';', i) != descriptor.lastIndexOf(';'))
{
StringBuilder buffer = new StringBuilder();
int i2 = i;
boolean isTypeDec = false;
while (i2 < descriptor.length()) {
char c1 = descriptor.charAt(++i2);
if (!isTypeDec && c1 == ';') {
break;
}
if (c1 == '<') {
isTypeDec = true;
continue;
}
if (c1 == '>') {
isTypeDec = false;
continue;
}
if (c1 == '.')
c1 = '$';
if (!isTypeDec) {
buffer.append(c1);
}
}
name = buffer.toString().replace('/', '.');
i = i2;
} else {
int i2 = descriptor.indexOf(';', i++);
name = descriptor.substring(i, i2).replace('/', '.');
i = i2;
}
{noformat}
Workaround: Workaround Exists

Hi,
When I try to run attached code compiled with javac I recive the following error:
{noformat}
Exception in thread "main" java.lang.RuntimeException: multiple descriptors?:

{noformat}
However if I run the same code from eclipse (ejc) i get expected result:
{noformat}
@javassist_test.Condition(condition=<javassist_test.A$B class>)
{noformat}
