Using parser debugging I found out, that the construct
new byte[1 << 16]
is the culprit. Changing this to
new byte[0x10000]
parses without problems.
Appears to be an error in the lexer. The following also fails:
{pre}public class X {
Object b = new Object();
int a = 1 << 30;
}{pre}
This is because the lexer does not reset it's state when it leaves a 'new block' and it does not properly account for when it is within a square bracket. In these situations < and > are not handled properly.
The attached patch fixes this issue. Please note, I have added a new file, FieldTest.java, with appropriate test cases for these field assignment scenarios. I didn't see an existing file that related to fields, thus the addition.
