JDBC syntax error at end of input

Hello,

I am trying to build a query using StringBuilder based off a variable
size ArrayList of inputs. When testing a simplest use case of one input
ID, I get an syntax error at end of input. However, if I copy the
generated SQL and run it in pgAdmin3, it is able to execute successfully.
Below is the error with loglevel2 enabled. Any advice would be much
appreciated.

SELECT seq_chromats.species_code_4, seq_chromats.fasta_header_line,
seq_chromats.fasta_sequence, seq_chromats.flag_two_reads_exist,
seq_amplicons.amplicon_name, seq_primers.primer_name FROM seq_amplicons
INNER JOIN seq_primers ON seq_primers.amplicon_name =
seq_amplicons.amplicon_name INNER JOIN seq_chromats ON
seq_chromats.primer_id = seq_primers.primer_id WHERE
seq_amplicons.amplicon_name IN (('0_8156_01'))
