FULL PRODUCT VERSION :
java version "1.8.0_66"
Java(TM) SE Runtime Environment (build 1.8.0_66-b18)
Java HotSpot(TM) 64-Bit Server VM (build 25.66-b18, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [Version 6.3.9600]

A DESCRIPTION OF THE PROBLEM :
When using an API that makes use of heavy overloading, lots of generics and type inference, javac can take extreme compilation times for trivial classes.

REGRESSION.  Last worked in version 7u76

ADDITIONAL REGRESSION INFORMATION: 
java version "1.7.0_67"
Java(TM) SE Runtime Environment (build 1.7.0_67-b01)
Java HotSpot(TM) 64-Bit Server VM (build 24.65-b04, mixed mode)

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Maven is not relevant for this bug, but the following pom.xml helps reproduce it more easily:

<project 
        xmlns="http://maven.apache.org/POM/4.0.0" 
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 
                            http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>compilation-issues</groupId>
    <artifactId>compilation-issues</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <build>
        <sourceDirectory>src</sourceDirectory>
        <plugins>
            <plugin>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.3</version>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                </configuration>
            </plugin>
        </plugins>
    </build>
    <dependencies>
        <dependency>
            <groupId>org.jooq</groupId>
            <artifactId>jooq</artifactId>
            <version>3.7.1</version>
        </dependency>
    </dependencies>
</project>

With the above Maven config, try compiling the following class that makes use of the jOOQ API:

import static org.jooq.impl.DSL.field;

import org.jooq.SQLDialect;
import org.jooq.impl.DSL;

public class Test {
    public void method() {
        DSL.using(SQLDialect.MYSQL)
           .select()
           .where(DSL.trueCondition())
           .and(field("client.id").eq(field("client_id")))
           .and(field("client.id").eq(field("client_id")))
           .and(field("client.id").eq(field("client_id")))
           .and(field("client.id").eq(field("client_id")))
           .and(field("client.id").eq(field("client_id")))
           .and(field("client.id").eq(field("client_id")))
           .and(field("client.id").eq(field("client_id")))
           .and(field("client.id").eq(field("client_id")))
           .and(field("client.id").eq(field("client_id")))
           .and(field("client.id").eq(field("client_id")))
        ;
    }
}

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The code should compile instantly.
ACTUAL -
It takes 22 seconds on my machine. Adding more ".and(...)" clauses to the statement makes things worse and worse

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
- Downgrading jOOQ to version 3.5.x
- Downgrading Java to 1.7
- Using the Eclipse compiler
- Any of the following equivalent classes, that don't rely as heavily on type inference:

import static org.jooq.impl.DSL.field;

import org.jooq.Field;
import org.jooq.SQLDialect;
import org.jooq.impl.DSL;

public class Test {
    public void method() {
        Field<Object> f1 = field("client.id");
        Field<Object> f2 = field("client_id");
        DSL.using(SQLDialect.MYSQL)
           .select()
           .where(DSL.trueCondition())
           .and(f1.eq(f2))
           .and(f1.eq(f2))
           .and(f1.eq(f2))
           .and(f1.eq(f2))
           .and(f1.eq(f2))
           .and(f1.eq(f2))
           .and(f1.eq(f2))
           .and(f1.eq(f2))
           .and(f1.eq(f2))
           .and(f1.eq(f2))
        ;
    }
}


or:


import static org.jooq.impl.DSL.field;

import org.jooq.Condition;
import org.jooq.SQLDialect;
import org.jooq.impl.DSL;

public class Test {
    public void method() {
        Condition condition = field("client.id").eq(field("client_id"));
        DSL.using(SQLDialect.MYSQL)
           .select()
           .where(DSL.trueCondition())
           .and(condition)
           .and(condition)
           .and(condition)
           .and(condition)
           .and(condition)
           .and(condition)
           .and(condition)
           .and(condition)
           .and(condition)
           .and(condition)
        ;
    }
}
